N-Functionalised TsDPEN catalysts for asymmetric transfer hydrogenation; synthesis and applications

Abstract

A series of Ru(II)/arene complexes containing N-alkylated derivatives of TsDPEN were prepared and tested in the asymmetric transfer hydrogenation (ATH) of ketones. The results demonstrated that a wide variety of functionality were tolerated on the basic amine of the TsDPEN ligand, without significantly disrupting the ability of the catalyst to catalyse hydrogen transfer reactions.
