In this study, heterobimetallic palladium-cobalt tetraacetate was used as the catalyst for intermolecular aziridination and amination reactions. 2,2,2-trichloroethanol synthesis of 2,2,2-Trichloroethyl sulfamate was used as the source of nitrene, and PdCo(OAc)4 as the catalyst to react with alkenes. And the products were aziridine and amine compound. PdCo(esp)2 as analog of PdCo(OAc)4, was synthesized and with a common catalyst for the comparison with palladium acetate, rhodium acetate, Rh2(esp)2 in their catalytic ability in nitrene insertion reaction.
