tested as a catalyst for hydrophosphination of alkynes, alkenes, and carbodiimides. Based on the collective evidence of stoichiometric reactions, NMR monitoring studies, kinetic analysis, and DFT calculations, a mechanism involving deprotonation, alkyne insertion, and protonolysis is proposed for the [iBu3AlHLi]2 aluminate catalyzed hydrophosphination of alkynes with diphenylphosphine. This study enhances
磷铝铝酸锂iBu 3 AlPPh 2 Li(THF)3已通过X射线晶体学和NMR光谱法合成,分离并表征,已被用作炔烃,烯烃和碳二亚胺的加氢磷酸化催化剂。基于化学计量反应,NMR监测研究,动力学分析和DFT计算的集体证据,提出了一种涉及去质子化,炔烃插入和质子分解的机理,用于[iBu 3 AlHLi] 2铝酸盐催化炔烃与二苯膦的加氢磷酸化反应。这项研究进一步促进了使用常见的可持续主族金属的无过渡金属,原子经济均相催化的发展。
