Nakayama, Yoshiki; Ando, Gaku; Abe, Manabu; Koike, Takashi; Akita, Munetaka published an article in ACS Catalysis. The title of the article was 《Keto-Difluoromethylation of Aromatic Alkenes by Photoredox Catalysis: Step-Economical Synthesis of α-CF2H-Substituted Ketones in Flow》.Synthetic Route of C10H16Br3N The author mentioned the following in the article:
A step-economical method for synthesis of α-CF2H-substituted ketones from readily available alkene feedstocks was developed. Radical difluoromethylation of aromatic alkenes combining DMSO oxidation and photoredox catalysis is a key to the successful transformation. Electrochem. anal., laser flash photolysis (LFP), and d. functional theory (DFT) calculations reveal that N-tosyl-S-difluoromethyl-S-phenylsulfoximine serves as the best CF2H radical source among analogous sulfone-based CF2H reagents. The present photocatalytic keto-difluoromethylation was applied to flow synthesis and easily scaled up to gram-scale synthesis within a reasonable reaction time. Furthermore, potentials of the α-CF2H-substituted ketones for useful synthetic intermediates are shown; e.g., synthesis of the CF2H-containing α-hydroxyamide with the same carbon skeleton as that of the anticonvulsant active CF3-analog, is disclosed. Addnl., mechanistic studies are also discussed. In addition to this study using Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, there are many other studies that have used Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide(cas: 111865-47-5Synthetic Route of C10H16Br3N) was used in this study.
Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide(cas: 111865-47-5) belongs to organobromine compounds.Organobromine chemicals are produced naturally by an array of biological and other chemical processes in our environment. Synthetic Route of C10H16Br3NSome of these compounds are identical to man-made organobromine compounds, such as methyl bromide, bromoform, and bromophenols, but many others are entirely new moleclar entities, often possessing extraordinary and important biological properties.
