Dicarbofunctionalizations of an Unactivated Alkene via Photoredox/Nickel Dual Catalysis.

Abstract

1,2-Dicarbofunctionalization of unactivated olefin has been reported under photoredox/nickel dual catalysis. The mildness of the visible-light-mediated reaction allows the use of various alkyl and aryl electrophiles with several sensitive functional groups. The protocol was equally applied for late-stage diversification of drugs and biologically active molecules. Investigations elucidated the importance of photoredox/nickel dual catalysis and α-amino-radical-mediated halogen atom transfer and provided us with the nickel complexes involved in the reaction.
