Angew Chem Int Ed Engl. 2014 May 12;53(20):5199-201. doi: 10.1002/anie.201400059. Epub 2014 Mar 14.

Abstract

A method of reductive amination without an external hydrogen source is reported. Carbon monoxide is used as the reductant. The reaction proceeds efficiently for a variety of carbonyl compounds and amines at low catalyst loadings and is mechanistically interesting as it does not seem to involve molecular hydrogen.

Keywords: amination; amines; atom economy; carbon monoxide; reduction.
