H. Amii et al., Mg-0-promoted selective C-F bond cleavage of trifluoromethyl ketones: a convenient method for the synthesis of 2,2-difluoro enol silanes, CHEM COMMUN, (14), 1999, pp. 1323-1324
2,2-Difluoro enol silyl ethers were readily prepared by Mg-0 promoted selec
tive defluorination of trifluoromethyl ketones in the presence of TMSCl, wh
ich involves C-F bond cleavage.
