A NOVEL AND CONVENIENT METHOD FOR TRIFLUOROMETHYLATION OF ORGANIC HALIDES USING CF3SiR'3/KF/Cu(I) SYSTEM
Urata, Hisao,Fuchikami, Takamasa
, p. 91 - 94 (1991)
Fluoride ion induced cross-coupling reaction of organic halides with trifluoromethyltrialkylsilanes takes place in the presence of Cu(I) salts under mild reaction conditions to give the corresponding trifluoromethylated products in high yields.
