α-芳硒基羰基化合物的合成(英文)

Synthesis of -Arylselenocarbonyl Compounds

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 Cp2 Ti Cl2 / 2 i- Bu Mg Br/ THF体系还原二芳基二硒醚得到。

Selenoketones and α selenoesters were prepared separately by the reaction of arylselenium complexes of titanocene(Cp 2TiSeAr) with α bromoketones and α bromoesters. Cp 2TiSeAr was derived from the reductive cleavage of diaryldiselenides by the system of Cp 2TiCl 2/2[WT5”BX]i [WT5”BZ]BuMgBr/THF.
