The reaction of alkynes with vinyl triflates in the presence of catalytic amounts of Pd(OAc)2 and HCOOK, omitting phosphane ligands, affords hydrovinylation products usually in good to high yields. The reaction has been employed to develop a regioselective synthesis of 3-vinylfuran-2(5H)-ones from methyl 4-hydroxy-2-butynoates.
在催化量的 Pd(OAc)2 和 HCOOK 存在下,炔烃与乙烯基三氟甲磺酸酯的反应,省略磷烷配体,通常以良好到高产率提供加氢乙烯基化产物。该反应已被用于从 4-羟基-2-丁酸甲酯开发 3-乙烯基呋喃-2(5H)-酮的区域选择性合成。
