A mild and general visible light photoredox catalysis-induced intermolecular three-component alkene 1,2-diarylation involving aryl C(sp2)-H functionalization is described. The key to controlling the chemoselectivity toward alkene 1,2-diarylation is the employment of a 2,2'-bipyridine base, thus allowing the formation of two new C(sp3)-C(sp2) bonds via aryl radical formation from aryldiazonium salts, addition across the Cdouble bond, length as m-dashC bonds, and aryl C(sp2)-H functionalization cascades.
