Preparation of α- or β-trifluoromethylated vinylstannanes and their cross-coupling reactions

α - or β-Trifluoromethylated vinylstannanes 1, 2a, 3 and 4 were prepared form 1,1-bis(phenylthio)-2,2,3,3,3-pentafluoropropylbenzene (5) via several steps. The cross-coupling arylation reactions of 1-4 with aryl iodides bearing a bromo, methoxy, methyl, n

Preparation of novel β,β-diphenyl α-(trifluoromethyl)vinylstannane and its cross-coupling reactions with aryl iodides

β,β-Diphenyl-α-(trifluoromethyl)vinylstannane 6 was prepared in good yield via several steps from 2,3,3,3-tetrafluoro-1-phenyl-1-phenylthiopropene. The cross-coupling reactions of 6 with aryl iodides in the presence of a catalytic amount of Pd(PPh3)4 and CuI provided trifluoromethylated triphenylethene derivatives 7 in high yields.
