Abstract

An efficient regio- and chemoselective dearomatization of a wide range of N-heteroarenes using hydrido-cobalt catalysts can be performed under mild conditions. Various quinolines and pyridines bearing electron-donating and electron-withdrawing substituents are compatible with this methodology.
