A mild CuBr–NMO oxidative system for the coupling of anilines leading to aromatic azo compounds

An efficient, mild and cost-effective method has been developed utilizing CuBr with N -methylmorpholine N -oxide (NMO/NMMO) for the oxidative coupling of anilines to access symmetrical and unsymmetrical azo compounds in high yield. The reactivity was found to be governed by electronic and steric fac...

Zusammenfassung:An efficient, mild and cost-effective method has been developed utilizing CuBr with N -methylmorpholine N -oxide (NMO/NMMO) for the oxidative coupling of anilines to access symmetrical and unsymmetrical azo compounds in high yield. The reactivity was found to be governed by electronic and steric factors of anilines.
