Abstract
Reaction of 2,3-diphenyl-2H-1,4-benzoxazin-2-ol with copper(II) nitrate in acetonitrile led to oxidative decomposition and formation of tetrakis(μ-benzoato-κ2O:O)bis(2-phenyl-1,3-benzoxazole-κN)dicopper(II) as the final product. The complex has been structurally characterized by X-ray crystallography. The presence of two unexpected ligands, 2-phenylbenzoxazole and benzoate, in the complex is attributed to the oxidative cleavage of 2,3-diphenyl-2H-1,4-benzoxazin-2-ol in the presence of copper(II) ions.
