Dual nickel- and photoredox-catalyzed reductive cross-coupling of aryl vinyl halides and unactivated tertiary alkyl bromides

Chem Commun (Camb). 2019 May 21;55(42):5918-5921. doi: 10.1039/c9cc00768g.

Abstract

A novel reductive cross-coupling of aryl vinyl halides and unactivated tertiary alkyl bromides has been realized via photoredox/nickel dual catalysis to produce vinyl arene derivatives bearing all-carbon quaternary centers with excellent E-selectivity. A stoichiometric metal reductant could be avoided by employing commercially available N,N,N',N'-tetramethylethylenediamine (TMEDA) as the terminal reductant.
