Gold-catalyzed aerobic oxidation of dibenzylamine Au(OAc)3 is applied as an effective catalyst of the selective  to dibenzylimine using molecular oxygen as the only oxidant. When Au(OAc)3 was preadsorbed onto CeO2, the supported catalyst was more active than any homogeneous or heterogeneous catalyst known for this reaction. Although, some fascinating color changes in the early stage of the...
