α-芳硒基羰基化合物的合成

摘要

α-Selenoketones and α-selenoesters were prepared separately by the reaction of arylselenium complexes of titanocene (Cp2 TiSeAr) with α- bromoketones and α- bromoesters.Cp2 TiSeAr was derived from the reductive cleavage of diaryldiselenides by the system of Cp2TiCl2/2i-BuMgBr /TF.%茂钛硒化物分别与α-溴代酮和α-溴代酯反应生成了相应的α-硒代酮和α-硒代酯,茂钛硒配合物由Cp2TiCl2/2i-BuMgBr/THF体系还原二芳基二硒醚得到.
