A TEMPO‐oxidized method has been developed for the synthesis of bis(indolyl)‐methane derivatives by the cross‐dehydrogenative coupling between C(sp3)–H of para‐cresol derivatives and C(sp2)‐H of indoles in moderate yields under aqueous conditions. This approach has significant advantages in avoiding prefunctionalization, using water as the solvent and tolerating various functional groups.
