Photoredox-Catalyzed Redox-Neutral Difluoroalkylation To Construct Perfluoroketones With Difluoroenoxysilanes
ORGANIC & BIOMOLECULAR CHEMISTRY(2021)
摘要
A mild and facile approach to construct various perfluoroketones via photo-catalyzed difluoroalkylation of difluoroenoxysilanes is developed. The reaction includes a strategy of combination of two fluorine-containing functional groups, which confers the reaction with characteristics like high efficiency, mild conditions, and broad scope. A variety of fluoroalkyl halides including perfluoroalkyl iodides, bromo difluoro esters and amides can be employed as radical precursors. Control experiments indicate that a single-electron transfer pathway may be involved in the reaction.
