Carbon monoxide-driven osmium catalyzed reductive amination harvesting WGSR power

Abstract

Herein, we present the first example of Os-catalyzed efficient reductive amination under water–gas shift reaction conditions. The developed catalytic systems are formed in situ in aqueous solutions, employ as small as 0.0625 mol% osmium and are capable of delivering reductive amination products for a broad range of aliphatic and aromatic carbonyl compounds and amines. The scope of the reaction, active catalytic systems, possible limitations of the method and DFT-supported mechanistic considerations are discussed in detail in the manuscript.
