The action of n-butyllithium in hexane on CF2BrCH=CH2/CF2=CHCH2Br (5:2 to 20:1 mixture) in 5:1:1 THF/Et2O/pentane at -95 deg C generates gem-difluoroallyllithium which may be trapped, generally in good yield, by an in situ procedure using triorganochlorosilanes (R3SiCF2CH=CH2) and aldehydes and ketones (RR'C(OH)CF2CH=CH2).
