The first photosensitizer‐free visiblelight‐driven, gold‐catalyzed C–C cross‐couplings of arylboronic acids and aryldiazonium salts are reported. The reactions can be conducted under very mild conditions, using a catalytic amount of tris(4‐trifluoromethyl)phosphinegold(I) chloride [(4‐CF3‐C6H4)3PAuCl] with methanol as the solvent allowing an alternative access to a variety of substituted biaryls in
