An efficient CuBr catalyzed cleavage of C–N bonds in the oxidative cross-dehydrogenative-coupling (CDC) of N-benzyl amines with indoles mediated by tert-butyl hydroperoxide (TBHP) was reported. A series of methine-bridged bis-indole derivatives were successfully synthesized under the optimized reaction conditions.
