halides with diaryl and dialkyl phosphines, as well as with dibutyl phosphite, is reported. This highly efficient transformation is realized through the use of copper(I) iodide as a catalyst, N,N'-dimethylethylenediamine as a ligand, and Cs(2)CO(3) as a base. A variety of sterically hindered and/or functionalized substrates were found to react under these reaction conditions to provide products in good
据报导了将芳基卤化物和乙烯基卤化物与二芳基和二烷基膦以及亚磷酸二丁酯偶联的一般方法。通过使用碘化铜(I)作为催化剂,N,N'-二甲基乙二胺作为配体和Cs(2)CO(3)作为碱,可以实现这种高效的转化。发现多种空间受阻和/或官能化的底物在这些反应条件下反应,以提供具有良好产率至优异产率的产物。[反应:看文字]
