설명

일반 설명

Material is complexed with up to 1 equivalent of ZnCl₂

Zinc difluoromethanesulfinate is a reagent widely used to incorporate difluoromethyl functionality onto biologically significant structural motifs. It is used to difluoromethylate compounds such as heteroarenes, thiols, enones, and α, β‐unsaturated carboxylic acids.[1]

애플리케이션

Zinc difluoromethanesulfinate (DFMS) is part of a zinc sulfinate toolbox developed by Phil Baran for the simple and rapid diversification of heterocycles.†

Practical and Innate Carbon-Hydrogen Functionalization of Heterocycles

DFMS is a new reagent for direct difluoromethylation of organic substrates via a radical process. This mild, operationally simple, chemoselective, and scalable difluoromethylation method is compatible with a range of nitrogen-containing heteroarene substrates of varying complexity as well as select classes of conjugated p−systems and thiols.†
