A CONVENIENT SYNTHESIS OF 2,2-DIFLUORO ENOL SILYL ETHERS FROM CHLORODIFLUOROMETHYL KETONES
Yamana, Masayuki,Ishihara, Takashi,Ando, Teiichi
, p. 507 - 510 (1983)
Various chlorodifluoromethyl ketones can be converted to the corresponding 2,2-difluoro enol silyl ethers in good yields, by the action of zinc dust and chlorotrimethylsilane in dry acetonitrile at 60 degC.
