An Efficient Protocol for Formylation of Amines Using Carbon Dioxide and PMHS under Transition-Metal-Free Conditions.

A highly efficient, green and simple base catalytic system was investigated for the formylation of amines using CO2 and PMHS [poly(methylhydrosiloxane)] under mild reaction conditions. This reaction proceeds smoothly without additives and furnishes the corresponding N-formylated products from both the 1° and the 2° aliphatic as well as aromatic amines in good to excellent yields.
