Abstract

An efficient methodology for the reductive alkylation of secondary amines with aldehydes and Et₃SiH using an iridium complex as a catalyst has been developed. In addition, a cheaper, easy-to-handle, and environmentally friendly reducing reagent such as polymethylhydrosiloxane (PMHS) in place of Et₃SiH was also useful.
