(E)-Trimethyl-(3,3,3-trifluoroprop-1-enyl)silane (1) was synthesized as a reagent for use In Hiyama cross-coupling reactions for the production of beta-trifluoromethylstyrene derivatives. Cross-coupling of 1 with electronically diverse aryl iodides was achieved by treatment with CsF In the presence of catalytic amounts of palladium to afford the desired products In moderate to good yields.
(E)-三甲基-(3,3,3-三氟丙烯基)硅烷(1)作为试剂用于HyRule接头反应,用于制备二氟甲基芳香族苯乙烯衍生物。在催化的钯存在下,1与电子多样性苯基卤化物反应,利用CsF提供接头试剂,得到了所需的产物,产率在中等到良好范围。
