Solvent-promoted catalyst-free N-formylation of amines using carbon dioxide under ambient conditions

Abstract

An unprecedented catalyst-free formylation of amines using CO₂ and hydrosilanes was developed. The solvent plays a vital role in promoting the interaction of amines with hydrosilanes and subsequent CO₂ insertion, thus facilitating the simultaneous activation of N–H and Si–H bonds. Based on relevant mechanistic studies, a plausible mechanism involving a silyl carbamate intermediate is proposed.
