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

[摘要] beta,beta -Diphenyl-alpha-(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.
