Mg0-promoted selective C–F bond cleavage of trifluoromethyl ketones: a convenient method for the synthesis of 2,2-difluoro enol silanes

2,2-Difluoro enol silyl ethers were readily prepared by Mg0 promoted selective defluorination of trifluoromethyl ketones in the presence of TMSCl, which involves C–F bond cleavage.
