Synthesis of imines from the coupling reaction of alcohols and amines catalyzed by phosphine-free cobalt(<scp>ii</scp>) complexes

Abstract

H NMR analyses. Most of the previously reported 3d transition metal catalysts used in imine synthesis reactions have a phosphine ligand environment, and the reactions were performed under inert conditions. Herein we have developed a sustainable route for the synthesis of imines from the coupling reaction of alcohols with amines under aerial reaction conditions using phosphine-free air stable cobalt catalysts.
