Abstract

We herein described a visible light induced nickel^(II)-catalyzed cross-coupling of secondary phosphine oxides with aryl halides. The Ni^(I) species and chlorine atom radical Cl˙ were generated via the ligand to metal charge transfer (LMCT) process of the NiCl₂(PPh₃)₂, which allows nickel^(IV)-phosphorus species in situ formation, giving various tertiary phosphine oxides under photocatalyst-free conditions.
