A large number of reagents have been developed for the synthesis of trifluoromethylated compounds. However, an ongoing challenge in trifluoromethylation reaction is the use of less expensive and practical trifluoromethyl sources. We report herein the unprecedented direct trifluoromethylation of (hetero)arenes using trifluoromethanesulfonic anhydride as a radical trifluoromethylation reagent by merging photoredox catalysis and pyridine activation. Furthermore, introduction of both the CF3 and OTf groups of the trifluoromethanesulfonic anhydride into internal alkynes to access tetrasubstituted trifluoromethylated alkenes was achieved. Since trifluoromethanesulfonic anhydride is a low-cost and abundant chemical, this method provides a cost-efficient and practical route to trifluoromethylated compounds.

Kinetic results are reported on the rates of enolisation of title compounds in water, in acetate buffers, in dilute hydrochloric acid, in dilute sodium hydroxide solutions and in the presence of several metal-ion salts, as measured by their rates of halogenation at 25 deg C.The results have been compared with those previously obtained from the corresponding reactions of acetophenone and a number of acetylheterocycles.It is shown that a suitable metal cation (e.g., Cu2+) can be hundreds of times more effective than the proton in catalysing the enolisation process of an acetylheterocyclic compound.This can be due either to the ‘soft’ character of the acetyl group, as, for example, that of 2-acetylpyrrole, or to coordination of both the carbonyl oxygen and the heteroatom by the metal cation in the transition state of the reaction, as for 2- and 4-acetylthiazoles.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.38205-66-2, Name is 1-(4-Thiazolyl)ethanone, molecular formula is C5H5NOS. In a Article£¬once mentioned of 38205-66-2, name: 1-(4-Thiazolyl)ethanone

Carboxylic acids were converted directly in 56-99% yields into methyl, n-butyl, and isopropyl ketones using excess cyanocuprates R2CuLi 3 LiCN. A substrate with a stereocenter alpha to the carboxylic acid was converted into ketones with very little loss of enantiomeric purity. A variety of functional groups were tolerated including aryl bromides. This direct transformation of a carboxylic acid into ketone with minimal tertiary alcohol formation is proposed to involve a relatively stable copper ketal tetrahedral intermediate.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 38205-66-2 is helpful to your research., name: 1-(4-Thiazolyl)ethanone

Herein we report a novel and straightforward protocol for the construction of valuable gem-BPs by means of proton-coupled electron-transfer (PCET)-triggered enamido C(sp2)?H diphosphorylation. This reaction represents a rare example of realizing the challenging double C?P bond formation at a single carbon atom, thus providing facile access to a broad variety of structurally diverse bisphosphonates from simple enamides under silver-mediated conditions. Initial mechanistic studies demonstrated that the diphosphorylation involves two rounds of PCET-initiated radical relay process.

Irradiation of thiabendazole in aqueous solution at lambda ? 290 nm resulted in 91.6% substrate transformation in 4 h. The degradation approximately followed first order kinetics; rate constant, 1.73 x 10-4 s-1; and half-life, 1.01 h. Irradiation under UV-light (lambda ? 290 nm) in the presence of fulvic and humic acids (isolated from soil, Scheyern, Germany) resulted in 90.8% and 88.4% degradation of the chemical respectively. Several products were isolated and their structure determined by GC-MS. Humic and fulvic acid seem to have little effect on photolysis of thiobendazole in water.
