Hydrophosphorylation of alkynes with dialkylphosphites in the various copper catalysts was investigated. The reactions provided the regio- and stereoselective -vinylphosphonates under commercially available copper chloride catalyst in the presence of ethylene diamine as an efficient ligand. The impact of solvents, temperature, and diamine ligands are included in this report. In addition, the DFT calculations provided insight into the regio- and stereoselectivity of the reaction. It is suggested that the reaction proceeded an generated Cu(AN) complex. The reaction of phenylacetylene with diethyl phosphite in the presence of EDA and the (CHCN)CuBF complex as a catalyst also gave the corresponding -vinylphosphonates in good yield.
研究了在各种铜催化剂存在下，炔烃与亚磷酸二烷基酯的氢磷酸化反应。在市售氯化铜催化剂存在下，以乙二胺作为有效配体，这些反应提供了区域和立体选择性的β-乙烯基膦酸酯。本报告包括了溶剂、温度和二胺配体的影响。此外，密度泛函理论（DFT）计算为该反应的区域和立体选择性提供了深入了解。有人认为该反应通过生成Cu(AN)络合物进行。在EDA和(CHCN)CuBF络合物作为催化剂存在下，苯乙炔与亚磷酸二乙酯的反应也以良好的产率得到了相应的β-乙烯基膦酸酯。
