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.
由2,3,3,3-四氟-1-苯基-1-苯基硫代丙烯经几个步骤以高收率制备了β,β-二苯基-α-(三氟甲基)乙烯基锡烷6。在催化量的Pd(PPh 3)4和CuI的存在下6与芳基碘的交叉偶联反应以高收率提供了三氟甲基化的三苯乙烯衍生物7。
