reported. Using acetylene at atmospheric pressure, the catalyst consisting of <1 mol% copper(I) phenylacetylide and a trialkyl bisphosphine ligand shows a high selectivity towards the formation of propargyl alcohol rather than 1,4-butynediol, which is not reported for common heterogeneous copper acetylide catalysts. The biphasic water/toluene reaction mixture allows the separation of targeted products with
报道了一种铜 (I)/膦体系,可均匀地催化甲醛与乙炔或末端炔烃的炔基化反应。在大气压下使用乙炔,由 <1 mol% 苯乙炔铜 (I) 和三烷基双膦配体组成的催化剂显示出对形成炔丙醇而不是 1,4-丁炔二醇的高选择性,这对于常见的非均相铜没有报道乙炔催化剂。双相水/甲苯反应混合物允许目标产物与水层分离,催化剂通过有机层再循环。
