catalyst for β-E regio- and stereoselective syn-addition of the H–P(O)-bond of diphenylphosphine oxide, H-phosphinates, dialkylphosphites to various alkynes in the synthesis of P(O)-containing alkenes. Without additives and ligands Cu(II)-compounds showed better results than CuI or Ni(acac)2. The catalytic system developed is tolerant to typical organic functional groups present in the alkynes and to the
Cu(acac)2是在P(O)合成中,β- E区域和立体选择性地将二苯膦氧化物,H-次膦酸酯,二烷基亚磷酸酯的H–P(O)键加成到各种炔烃上的新型通用催化剂)的烯烃。没有添加剂和配体,Cu(II)化合物显示出比CuI或Ni(acac)2更好的结果。所开发的催化系统对炔烃中存在的典型有机官能团以及H-P(O)化合物中不同取代基的性质具有耐受性。
