A sustainable boron-based catalytic approach for chemoselective N-alkylation of primary and secondary aromatic amines and amides with primary, secondary, and tertiary benzylic alcohols has been presented. The metal-free protocol operates at low catalyst loading, tolerates several functional groups, and generates H2O as the sole byproduct. Preliminary mechanistic studies were performed to demonstrate
提出了一种可持续的基于硼的催化方法,用于伯,仲和叔苄醇对伯和仲芳族胺和酰胺的化学选择性N-烷基化。不含金属的方案在低催化剂负载下运行,可耐受多个官能团,并生成H2O作为唯一的副产物。进行了初步的机理研究,以证明硼催化剂在中间体二苄基醚的活化中的关键作用,并确定了决定速率的步骤。
