Transition metal-catalyzed reductive coupling has emerged as a powerful method for the construction of C–C bonds. Herein, a crystalline hydrate, Na2HPO4·7H2O, has been disclosed as an effective promoter for the reductive coupling of nitrodienes with unactivated alkenes to afford diverse dienes with various functionalities in an open-flask manner. The mechanism study has revealed that Na2HPO4·7H2O accelerates
过渡金属催化的还原偶联已成为构建C–C键的有效方法。在此,已经公开了结晶水合物Na 2 HPO 4 ·7H 2 O作为有效的促进剂,用于硝基二烯与未活化的烯烃的还原偶联,从而以开瓶的方式提供具有各种功能的各种二烯。机理研究表明,Na 2 HPO 4 ·7H 2 O促进了活性硅烷PhSi(OEt)H 2的原位生成并阻止了催化剂的失活。该方法也可以提高先前的还原偶联反应的效率。
