So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Inukai, Norie; Kawai, Tsuyoshi; Yuasa, Junpei researched the compound: 1-Iodo-2-methylbutane( cas:616-14-8 ).Computed Properties of C5H11I.They published the article 《Two Distinct Thermal Stabilities of DNA and Enzymatic Activities of DNase I in a Multistep Assembly with Carbazole Ligands: Different Binding Characteristics for Duplex and Quadruplex DNA》 about this compound( cas:616-14-8 ) in Chemistry – A European Journal. Keywords: DNA DNase I multistep carbazole ligand duplex quadruplex. We’ll tell you more about this compound (cas:616-14-8).

A partially hydrophobic carbazole ligand ((Im+)2Cz: 2,2′-(9-ethyl-9 H-carbazole-3,6-diyl)bis(ethyne-2,1-diyl)bis(1,3-dimethyl-1 H-imidazol-3-ium)) adopts two different binding states (binding states I and II) in its interactions with calf-thymus (ct-) DNA. Two distinct binding states were identified by biphasic UV/Vis and CD spectral changes during the titration of DNA into the carbazole ligand. At low concentrations of ct-DNA, (Im+)2Cz binds to nearly every part of ct-DNA (binding state I). By contrast, an increased concentration of ct-DNA results in a switch in the DNA-binding state, so that the ligands are bound per five DNA base pairs. Similarly, a monocationic carbazole ligand (Im+Cz: 2-((6-bromo-9-ethyl-9 H-carbazol-3-yl)ethynyl)-1,3-dimethyl-1 H-imidazol-3-ium) also shows biphasic UV/Vis spectral changes during the titration of ct-DNA into Im+Cz, which suggests two different binding states of the Im+Cz ligand with ct-DNA. The stepwise equilibrium of the ligand-DNA-complex formation is capable of switching the thermal stability of ct-DNA, as well as the enzymic activity of DNase (DNase I). In binding state I, the (Im+)2Cz ligands interact with nearly every base pair in ct-DNA and stabilize the double-helix structure, which results in a larger increase in the melting temperature of the ct-DNA than that observed with binding state II. On the other hand, the (Im+)2Cz ligand significantly reduces the enzymic activity of DNase I in binding state I, although the enzymic activity is recovered once the binding state of the ligand-DNA complex is changed to binding state II. The (Im+)2Cz ligand was also employed as a binder for G-quadruplex DNA. In contrast to the stepwise complex formation between (Im+)2Cz and ct-DNA, (Im+)2Cz shows a monotonous UV/Vis spectral response during the titration of G-quadruplex DNA into (Im+)2Cz, which suggests a single binding state for (Im+)2Cz with G-quadruplex DNA.

Pyridinium poly(hydrogen fluoride) (30% pyridine-70% hydrogen fluoride): a convenient reagent for organic fluorination reactions.

Pyridinium polyhydrogen fluoride (30% pyridine-70% HF) reagent, a stabilized, less-volatile form of HF, is a convenient and effective fluorinating agent. Fluorination, halofluorination, nitrofluorination, and hydrofluorination of olefins were achieved using the reagent. The in situ diazotization and subsequent fluorinative dediazonization of α-amino acids, aminoarenes, and carbamates yielded α-fluorocarboxylic acids, aryl fluorides, and fluoroformates, resp. Geminal dihalides and α-halo ketones were treated with HgO in pyridinium polyhydrogen fluoride to form geminal difluorides and α-fluoro ketones. Solutions of alkali halides in pyridinium polyhydrogen fluoride were also effective halogenating agents for aminoarenes, via in situ diazotization and subsequent nucleophilic dediazonization by the corresponding halides, as well as for alcs., via SN2 displacement reactions. Diazo ketones and diazoalkanes also reacted smoothly with halide ions in pyridinium polyhydrogen fluoride solution to give the corresponding geminally halofluorinated compounds Proper precautions must be observed in using pyridinium polyhydrogen fluoride.
