Ball milling of calcium carbide (CaC2) enables the reaction of its ethynyl moiety with organic electrophiles. This was realized simply by co-milling CaC(2)with organic substrates in a sealed jar without the need for an additive or a catalyst. Various ketones including those bearing alpha-hydrogens were ethynylated in good yields at short reaction times. Aryl halides are also amenable substrates for this protocol as they furnish aryl ethynes through a benzyne intermediate. This method offers a practical and cheap alternative to the established procedures for introducing ethynyl functionalities.

Some antagonistic bacteria contribute to the management of plant diseases by stimulating the host natural defense and/or by providing direct biocontrol of pathogens. The objective of this study was to evaluate the biocontrol performances and the ability to induce a systemic response to crown gall of four strains belonging to Bacillus and Pseudomonas genera. Evaluation of in vitro antagonistic ability showed that the four bacteria had a different spectrum of activity against the three tested strains of Agrobacterium tumefaciens. A delay in time of appearance and a significant reduction of the tumor size were observed in tomato plants obtained by bio-primed seeds and stem inoculated with A. tumefaciens. Seed priming with antagonistic strains stimulated some systemic defense mechanisms in tomato plants that can be related to the reduction of disease symptoms induced by A. tumefaciens. Both antagonists and A. tumefaciens strains induced variations in phenol content and peroxidase activity while polyphenol oxidase activity was mainly affected by the single A. tumefaciens strain. The response was different in relation to the various combinations of antagonist/pathogen, however Pseudomonas brassicacearum EPR3 strain was the most effective strain.

We report a set of electrochemically regulated protocols for the divergent synthesis of ketones and beta-keto esters from the same beta-hydroxycarboxylic acid starting materials. Enabled by electrochemical control, the anodic oxidation of carboxylic acids proceeded in either a one-electron or a two-electron pathway, leading to a 1,4-aryl transfer or a semipinacol-type 1,2-group transfer product with excellent chemoselectivity. The 1,4-aryl transfer represents an unprecedented example of carbon-to-oxygen group transfer proceeding via a radical mechanism. In contrast to previously reported radical group transfer reactions, this 1,4-group transfer process features the migration of electron-rich aryl substituents. Furthermore, with these chemoselective electrochemical oxidation protocols, a range of ketones and beta-keto esters including those possessing a challenging-to-access medium-sized ring could be synthesized in excellent yields.

Category: thiomorpholine. The Name is Anthrone. Through research, I have a further understanding and discovery of 90-44-8.

A new aromatic diamine, 10,10-bis [4-(4-amino-2-pyridinoxy)phenyl]-9(10H)-anthracenone (BAPPA) was synthesized from anthrone as the starting material, and the corresponding pyridine- and anthrone-containing poly(ether amide)s (PEAs) were prepared from BAPPA with various aromatic diacid chlorides via a low-temperature solution polycondensation. The resulting PEAs having number-average molecular weights (M-n) of 29,500-33,400 g/mol with the polydispersity index ranged from 1.75 to 1.84, were all amorphous, and displayed excellent thermal stability with the glass transition temperatures of 263-355 degrees C, the temperatures of 415-441 degrees C at 5% weight loss and the higher than 50% residues at 800 degrees C in nitrogen. These new PEAs were soluble in polar solvents such as N-methyl-2-pyrrolidone, N,N-dimethylacetamide and pyridine, even almost in tetrahydrofuran at room temperature and could form transparent, strong and flexible films with tensile strengths of 84-97 MPa, tensile moduli of 2.1-3.2 GPa and elongations at break of 4-13%. Also, the present PEAs exhibited high optical transparence with the UV cutoff wavelength in the 342-362 nm range, and 83-90% transmittance at 500 nm. These results indicated the introduction of anthrone and pyridine groups into the backbone could improve the solubility and transparence of polyamides.

Lymphomas (cancers of the lymphatic system) account for 12% of malignant diseases worldwide. Burkitt’s lymphoma (BL) is a rare form of non-Hodgkin’s lymphoma in which the cancer starts in the immune B-cells. We report the synthesis and preliminary studies on the antiproliferative activity of a library of 9,10-dihydro-9,10-ethanoanthracene based compounds structurally related to the antidepressant drug maprotiline against BL cell lines MUTU-1 and DG-75. Structural modifications were achieved by Diels-Alder reaction of the core 9-(2-nitrovinyl)anthracene with number of dienophiles including maleic anhydride, maleimides, acrylonitrile and benzyne. The antiproliferative activity of these compounds was evaluated in BL cell lines EBV- MUTU-1 and EBV+ DG-75 (chemoresistant). The most potent compounds 13j, 15, 16a, 16b, 16c, 16d and 19a displayed IC50 values in the range 0.17-0.38 mu M against the BL cell line EBV- MUTU-1 and IC50 values in the range 0.45-0.78 mu M against the chemoresistant BL cell line EBV+ DG-75. Compounds 15, 16b and 16c demonstrated potent ROS dependent apoptotic effects on the BL cell lines which were superior to the control drug taxol and showed minimal cytotoxicity to peripheral blood mononuclear cells (PBMCs). The results suggest that this class of compounds merits further investigation as antiproliferative agents for BL.

beta-Cyclodextrin-functionalized carbon nitride nanosheets were modified with a molecularly imprinted polymer to obtain a fluorescent probe of type MIP@beta-CD/CNNS which is shown to enable fluorometric determination of sterigmatocystin (STG). The material was characterized by transmission electron microscopy, infrared spectra, powder X-ray diffraction, X-ray photoelectron spectroscopy, and by absorption and emission spectra. The modified CNNSs have a good fluorescence quantum yield (13%), high sorption capacity for STG (86 mg center dot g(-1)), fast adsorption rate (25 min), and superior adsorption selectivity (with an imprint factor 2.56). When used as an optical probe for STG, the CNNSs act as the chromophore, while beta-CD and MIP act as the recognition groups. The blue fluorescence of MIP@beta-CD/CNNS (with excitation/emission maxima at 368/432 nm) is quenched by STG. Fluorescence drops linearly in the 0.15 to 3.1 mu M STG concentration range. The lower detection limit is 74 nM. The method was successfully applied to the determination of STG in spiked wheat extract. Conceivably, this detection scheme based on a combination of beta-CD inclusion and molecular imprinting may be extended to the detection of various other organic compounds.

10,10-Bis[4-(4-aminophenoxy)-3-methylphenyl]-9(10H)-anthrone, as a novel aromatic diamine, was synthesized from anthrone by three-step process. A series of polyimides containing methyl substituents and 9(10H)-anthrone pendant groups was prepared from this diamine with various aromatic dianhydridesviathe poly(amic acid) (PAA) precursors and subsequent thermal or chemical imidization procedure. Inherent viscosities of PAAs are between 0.87 and 1.58 dL/g, and the corresponding polyimides have the weight-average molecular weight and number-average molecular weight in the range of 49,400-64,200 and 28,700-37,700, respectively. Most of the polyimides obtained through the chemical cyclodehydration method are soluble in NMP, DMF, DMAc, Py andm-cresol at room temperature. These polyimides have glass transition temperatures of 289-313 degrees C, 10% weight loss temperatures of 484-524 degrees C, char yields of 55-63% at 800 degrees C, and temperature at the maximum-rate degradation of 560-584 degrees C in nitrogen, respectively. The polyimide films obtained through the thermal imidization have tensile strength of 76.43-119.74 MPa, elongation at break of 6.93-12.33%, and tensile modulus of 1.91-2.38 GPa.

I found the field of Chemistry very interesting.

The tricyclic aromatic ketone 9-anthrone and its derivatives are under basic conditions in equilibrium with their corresponding anionic forms. Unlike the neutral species, the 9-anthrolate anions can be excited by blue LED light and thus, are able to initiate a photoinduced electron transfer (PET) reaction. To demonstrate the synthetic applicability of the catalytic system, various (hetero)aryl chlorides were converted in C-C and C-Het bond-forming reactions affording the corresponding arylation products in moderate to excellent yields. The reactions proceed under very mild conditions without the need for a sacrificial electron donor. Besides 9-anthrone, other closely related derivatives were synthesised and investigated concerning their ability to catalyse demanding reductive transformations. Based on spectroscopic findings and radical trapping experiments a conceivable mechanism is proposed.

Ecological wastewater treatment plant (EWWTP), a kind of emerging wastewater treatment plant (WWTP) in recent years, combined microbiology with botany which is efficient for the removal of nitrogen and organic matter, as well as deodorization. The occurrence and removal of micro-organic pollutants in EWWTPs were still not well known. Polycyclic aromatic hydrocarbons (PAHs) and their typical derivatives (SPAHs) including the oxygenated PAHs (OPAHs), chlorinated PAHs (ClPAHs), and methyl PAHs (MPAHs) were investigated in an EWWTP in Guangdong Province, China. The concentrations of the sigma 6 OPAHs (114-384ng/L) were higher than the sigma 16 PAHs (92-250ng/L), and much higher than the sigma 4 MPAHs (13-64ng/L) and sigma 9 ClPAHs (2-3ng/L) in the EWWTP and the effluent receiving river. The total removal efficiencies of the PAHs, OPAHs, MPAHs, and ClPAHs in the EWWTP (43 +/- 14%, 41 +/- 7%, 55 +/- 16%, and 18 +/- 4%) were lower than the traditional WWTPs, probably due to the lower concentration of the sludge in the ecological treatment. The advanced treatment process (microfiltration and UV disinfection treatment) contributed much less (0-20%) to the whole removal efficiency than the ecological treatment (80-100%). The effluent from the EWWTP slightly reduced the PAHs and SPAHs concentrations in the receiving river. The high concentrations of the PAHs and SPAHs in the receiving river were similar to the influent of the EWWTP, indicating that some untreated wastewater was directly discharged to the river, especially in the upstream.

The oxidation of a series of alkylaromatic compounds with H2O2 catalyzed by an imine-based non-heme iron complex prepared in situ by reaction of 2-picolylaldehyde, 2-picolylamine, and Fe(OTf)(2) in a 2 : 2 : 1 ratio leads to a marked chemoselectivity for aromatic ring hydroxylation over side-chain oxidation. This selectivity is herein investigated in detail. Side-chain/ring oxygenated product ratio was found to increase upon decreasing the bond dissociation energy (BDE) of the benzylic C-H bond in line with expectation. Evidence for competitive reactions leading either to aromatic hydroxylation via electrophilic aromatic substitution or side-chain oxidation via benzylic hydrogen atom abstraction, promoted by a metal-based oxidant, has been provided by kinetic isotope effect analysis.
