Room Temperature C-P Bond Formation Enabled by Merging Nickel Catalysis and Visible-Light-Induced Photoredox Catalysis

A novel and efficient C-P bond formation reaction of diarylphosphine oxides with aryl iodides was achieved by combining nickel catalysis and visible-light-induced photoredox catalysis. This dual-catalytic reaction showed a broad substrate scope, excellent functional group tolerance, and afforded the corresponding products in good to excellent yields. Compared with the previously reported use of photoredox/nickel dual catalysis in the construction of C-C bonds, the methodology described herein was observed to be the first to allow for C-heteroatom bond formation.
