Descripción

Descripción general

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.

Aplicación

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.†
