Recommanded Product: 3-Nitrobenzaldehyde. The Name is 3-Nitrobenzaldehyde. Through research, I have a further understanding and discovery of 99-61-6.

Liquid phase tandem Knoevenagel-Michael condensation of various aromatic and heteroaromatic aldehydes with barbituric acid or 2-thiobarbituric acid and malononitrile was studied in a one-pot three-component reaction. For the first time, TMDP was employed as a safe and efficient solvent and/or catalyst in the liquid and aqueous ethanol medium, respectively, for the practical and eco-friendly Knoevenagel-Michael condensation. The reactions were carried out by using greener procedures, including a) the use of TMDP as an N-heterocycle organocatalyst in a green medium including water and ethanol (1:1 v/v) at reflux temperature, and b) the use of TMDP as a dual solvent-catalyst at 65 degrees C in the absence of any solvent. High to excellent yields of the desired pyrano[2,3-d] pyrimidinones were obtained under the two earlier mentioned conditions. The current methodologies have advantages, including (a) avoiding hazardous, toxic, volatile, and flammable materials and solvents, (b) avoiding tedious processes, harsh conditions, and multiple steps for the preparation of catalysts, (c) using a less toxic and noncorrosive catalyst, (d) minimizing hazardous waste generation and simple workup process, and (e) high recyclability of TMDP. Another important result of this work is that the TMDP can be a promising alternative for toxic, volatile, and flammable base reagents such as piperidine and triethylamine in liquid phase organic syntheses owing to its unique properties such as being less toxic, nonflammable, and nonvolatile, and having a low melting point, broad liquid range temperature, high thermal stability, and safe handling and storage.

Laccases produced by Leucoagaricus gongylophorus act in lignocellulose degradation and detoxification processes. Therefore, the use of L. gongylophorus laccase (Lac1Lg) was proposed in this work for degradation of anthracene and others polycyclic aromatic hydrocarbons without the use of mediators. Degradation reactions were performed in buffer aqueous solution with 10 ppm of anthracene and other PAHs, Tween-20 in 0.25% v/v and a laccase preparation of 50 U. The optimum condition (pH 6.0 and 30 degrees C) was determined by response surface methodology with an excellent coefficient of determination (R-2) of 0.97 and an adjusted coefficient of determination (R-adj(2)) of 0.93. In addition, the employment of the mediator ABTS decreased the anthracene biodegradation from 44 +/- 1% to 30 +/- 1%. This optimum pH of 6.0 suggests that the reaction occurs by a hydrogen atom transfer mechanism. Additionally, in 24 h Lac1Lg biodegraded 72 +/- 1% anthracene, 40 +/- 3% fluorene and 25 +/- 3% phenanthrene. The yellow laccase from L. gongylophorus biodegraded anthracene and produced anthrone and anthraquinone, which are interesting compounds for industrial applications. Moreover, this enzyme also biodegraded the PAHs phenanthrene and fluorene justifying the study of Lac1Lg for bioremediation of these compounds in the environment.

The electrochemical three-component assembly of isoquinolines has been accomplished by ruthenaelectro-catalyzed C-H/N-H functionalization. The robustness of the electrocatalysis was reflected by an ample substrate scope, an efficient electrooxidation, and an operationally friendly procedure. The isolation of key intermediates and detailed mechanistic studies, including unprecedented cyclovoltammetric analysis of a seven-membered ruthenacycle, provided support for an unusual ruthenium(II/III/I) regime.

The rapid cis-trans isomerization of alpha-anionic stilbene was regioselectively controlled by using flow microreactors, and its reaction with various electrophiles was conducted. The reaction time was precisely controlled within milliseconds to seconds at -50 degrees C to selectively give the cis- or trans-isomer in high yields. This synthetic method in flow was well-applied to synthesize precursors of commercial drug compound, (E)- and (Z)-tamoxifen with high regioselectivity and productivity.

We report detailed Rainan spectra for the neutral and radical anion forms of benzophenone, fluorenone, 2,2′-bipyridyl, 4,4′-di-tert-butyl-2,2′-dipyridyl, and anthracene. Density functional theory (DFT) predictions for the Raman spectra of these molecules give additional insight into the assignment of each vibrational mode. While the use of DFT has been problematic in quantifying the thermochemistry of highly delocalized radicals, we find that DFT-predicted spectra using the popular B3LYP functional are in excellent agreement with the observed Raman spectra. In the case of the two bipyridyl compounds, the Raman spectra allowed us to conclude that the cis form of the radical anion complexed to a sodium cation was the preferred configuration. Benzophenone and fluorenone radical anions gave a significantly weakened C=O bond stretching vibrational frequency as expected from the population of an antibonding pi* orbital. For benzophenone, the C=O vibration dropped from 1659 to 1403 cm(-1) upon reduction. Similarly, fluorenone showed a C=O vibration observed at 1719 cm(-1) for the neutral form that decreased to 1522 cm(-1) for the radical anion. The structurally rigid anthracene showed relatively smaller Raman band shifts upon single-electron reduction as the pi* orbital is more equally delocalized on the entire structure. In total, we correlated 65 DFT-predicted vibrational modes for the neutral molecules with an overall error of 7.1 cm(-1) (root-mean-square errors (RMSEs)) and 67 DFT-predicted vibrational modes for radical anions with an overall error of 9.9 cm(-1). These comparisons between theory and experiment are another example to demonstrate the power of DFT in predicting the identity and geometry of molecules using Raman spectroscopy.

A novel helical poly(phenyl isocyanide) bearing Boc protectedl-proline pendants (poly-1(m)) was designed and synthesized. Removed the protecting Boc groups on thel-proline pendants led to the formation of helical polymer poly-2(m), which showed high optical activity owing to the preferred right-handed helix of polyisocyanide main chain. Optically active helical poly-2(m)showed excellent catalytic ability on asymmetric aldol reaction. Helical polymer catalysts exhibited enhanced stereoselectivity in aldol reaction compared to small moleculel-proline. Under the optimized aldol reaction condition, the enantiomeric excess (ee) and diastereomeric ratio (dr) values of the aldol reaction product were respectively up to 90% and > 20/1. Moreover, the helical polyisocyanide catalyst Poly-2(m)can be easily recovered and reused in the aldol reaction for at least five cycles with maintained its activity and stereoselectivity.

The volatile compounds of Jiaozi-steamed breads (JSBs) fermented by Jiaozi starters from eight regions in China were extracted using simultaneous distillation and extraction (SDE) and headspace solid-phase microextraction and determined using gas chromatography-mass spectrometry (GC-MS). 1-Hexanol, 3-methyl-1-butanol, phenylethyl alcohol, benzaldehyde, naphthalene, ethanol, acetic acid, and n-hexadecanoic acid were the main volatiles of JSBs. Principal component analysis exhibited that the volatiles of JSBs from Nanyang City, Xi’an City, and Zhumadian City was negatively correlated to that of other five JSB samples. Cluster analysis demonstrated that the volatile characteristics of JSBs from Heze City, Minqin County, Taian City, Weinan City, and Yuncheng City belonged to a category, and the JSBs of Nanyang City, Xi’an City, and Zhumadian City were different from other five JSBs. It demonstrated that the volatile components of steamed breads in North China and South China were different. Practical applications From this study, it can be seen that simultaneous distillation and extraction (SDE) can completely extract volatile compositions of steamed breads fermented by Chinese traditional starter Jiaozi. SDE/GC-MS was suitable for the analysis of JSBs volatile composition. The relative contents of 1-hexanol, 3-methyl-1-butanol, phenylethyl alcohol, benzaldehyde, naphthalene, ethanol, acetic acid, and n-hexadecanoic acid in JSBs were at high level, and their contents could be used as a marker to identify JSBs. The volatile compositions of JSBs made of Jiaozi starters from Heze City, Minqin County, Taian City, Weinan City, and Yuncheng City were similar. However, JSBs of Nanyang City, Xi’an City, and Zhumadian City were different from other five JSBs. The volatile components of steamed breads in North China and South China were different, which reflected the difference in dietary habit in the southern and northern areas of China.

In recent years, heavy metal ions and nitroaromatic explosives in environmental pollutants have been a serious threat to human health due to their high toxicity, carcinogenicity, and nondegradability. The detection of metal ions and nitroaromatics has become an urgent problem. In this paper, a new water stable luminescent Eu-based metal-organic framework ([Eu(L)(DMF)(2)](n)) was prepared by the reaction of rigid ligand H3L (3,5-bis-(3-carboxyphenoxy)benzoic acid) and Eu (NO3)(3)center dot 6H(2)O under solvothermal conditions. Luminescent detection of the nitroaromatic compounds and metal ions showed that the complex had high sensitivity to Fe3+, o-nitrophenol, p-nitrophenol, and m-nitrophenol.

The present protocol uncover a new strategy to synthesize highly efficient solid TEMPO based catalyst in which 4-oxo-TEMPO was covalently tethered to the surface of amine functionalized magnetic titania. The chemical nature and structure of the synthesized catalyst was authenticated by various techniques such as Fourier transform infrared spectroscopy, thermogravimetric analysis, X-ray powder diffraction, field emission gun scanning electron microscopy, high resolution transmission electron microscopy, energy dispersive X-ray spectroscopy, elemental analysis, and vibrating sample magnetometer. FT-IR confirmed the immobilization of titania, APTES, and TEMPO on the magnetic nanoparticles. Thermal behaviour of the catalyst was studied by TGA. Morphology of the catalyst was investigated by FEG-SEM and HR-TEM analysis. Furthermore, loading content of TEMPO on the catalyst was quantified by elemental analysis and found to be 0.61 mmol/g. Magnetic properties of the catalyst were investigated by VSM analysis. The catalytic performance of the synthesized catalyst has been investigated for the oxidative synthesis of benzimidazoles, oxidative aromatization of 1,4-dihydropyridines, and oxidative trimerization of indoles using molecular oxygen. In addition, the catalyst could be successfully recycled and reused up to five times without the prominent loss of catalytic activity.
