An efficient copper-catalyzed method has been developed for Sonogashira couplings of aryl halides with terminal alkynes in water. The protocol uses inexpensive CuBr as the catalyst, 1,10-phenanthroline as the ligand, tetrabutylammonium bromide (TBAB) as the phase-transfer catalyst, environmentally friendly water as the solvent, and various internal alkynes were synthesized in good to excellent yields
已开发出一种有效的铜催化方法,用于芳基卤化物与末端炔烃在水中的 Sonogashira 偶联。该协议使用廉价的 CuBr 作为催化剂, 1,10-菲咯啉作为配体, 四丁基溴化铵 (TBAB) 作为相转移催化剂, 环保水作为溶剂, 并以良好的收率合成了各种内炔。
