Cobalt-catalyzed electrooxidative C-H/N-H [4+2] annulation with ethylene or ethyne

Abstract

Catalytic methodologies that incorporate commodity chemicals ethylene and ethyne into fine chemicals are quite limited. Here, the authors show a cobalt-catalyzed electrochemical C-H/N–H [4+2] annulation of aryl/vinyl amides with ethylene or ethyne to produce N-heterocycles in absence of oxidants.
