Abstract

A desulfurizing difluorination reaction of benzyl sulfides having a functional group such as an ester, a ketone, a nitrile, or an amide was performed by a reaction with IF5. Consequently, gem-­difluoro compounds could be obtained selectively.

Key words

fluorination - desulfurization - hypervalent iodine - oxidation - sulfide
