Cobalt‐Catalyzed Dehydrogenative Coupling of Amines into Imines

Primary amines have been subjected to an acceptorless dehydrogenative homo‐ and heterocoupling into imines with a cobalt catalyst. The catalytically active species are composed of cobalt nanoparticles, which are generated in situ by heating Co 2 (CO) 8 in the presence of trioctylphosphine oxide as a surfactant. The nanoparticles have been characterized by transmission electron microscopy where the image showed spherical and small particles with...
