摘要

Abstract Diarylcarbodiimides or benzylphenylcarbodiimides are converted to 1, 2- disubstituted benzimidazoles or 1, 2-disustituted quinazolines via addition/intramolecular C [BOND] H bond activation/CN or C [BOND] C bond forming reaction using copper (II) acetate/oxygen [Cu (OAc) 2/O 2] as the oxidant at 100 C in one-pot cascade procedure.
