Product 1

HCID 11205884Silane, trimethyl(trifluoroethenyl)-

Procedure

Chlorotrifluoroethylene of the formula (7) is treated with n-butyl lithium and then reacted with chlorotrimethylsilane of the formula (8) to obtain 1,1,2-trifluoro-2-trimethylsilylethylene of the formula (9). Then, without isolation, this compound (9) is reacted further with a lithium compound of the formula (10) to obtain a difluoroethylene compound of the formula (11).
