A highly chemoselective C-H arylation of phenylureas has been accomplished using dual palladium-photoredox catalysis at room temperature without any additives, base or external oxidants. Regioselective C-H arylation of N,N'-diaryl substituted unsymmetrical phenylureas has also been accomplished by a careful choice of aryl groups.
