摘要：
The reaction of a Ni-II complex and meta-chloroperoxybenzoic acid (m-CPBA) resulted in the formation of a long-lived Ni-III-chlorobenzoate complex that is a capable hydrocarbon oxidant. Analysis of the postreaction decay products showed the formation of oxidised derivatives of the supporting ligand (a benzoxazine), and heterolytic O-O bond scission in m-CPBA. This evidence indicates formation of a more potent transient Ni-III-oxyl species, which was further supported by DFT calculations.
