A new type of Cp*Ir complex bearing a functional 2,2'-bibenzimidazole ligand was designed, synthesized, and found to be a highly effective and general catalyst for the N-methylation of a variety of amines with methanol in the presence of a weak base (0.3 equiv of CsCO).
设计、合成了一种新型的含有功能化 2,2'-联苯并咪唑配体的 Cp*Ir 配合物，发现其在弱碱（0.3 当量的 CsCO）存在下，用甲醇作为甲基供体，可高效、普适地催化多种胺的 N-甲基化反应。
