Abstract

We report here a highly efficient cobalt-catalyzed hydroaminomethylation of alkynes with aminals towards tertiary allyl amines. The reaction occurs through a strategy of visible light photoredox cobalt dual catalysis. Excellent regio- and stereoselectivities have been obtained with unsymmetrical aryl alkyl or dialkyl internal alkynes.
