Abstract

Surface functionalization of SBA-15 followed by its reaction with Cu(OAc)(2) has been carried out to develop a new Cu-grafted functionalized mesoporous material, which catalyzes one-pot three component coupling of different aryl halides with thiourea and benzyl bromide in aqueous medium to produce aryl thioethers in very good yields (80-88%).

摘要

通过对 SBA-15 进行表面功能化，然后与 Cu(OAc)(2)反应，开发了一种新的 Cu 接枝功能化介孔材料，该材料在水相介质中催化不同芳基卤化物与硫脲和溴化苄的一锅法三组分偶联反应，以高产率（80-88%）生成芳基硫醚。
