Synthesis, Crystal Structures and Catalytic Oxidation Property of Copper(II) Complexes Derived from 5-Bromo-2-((2-diethylaminoethylimino)methyl)Phenol
Two new copper(II) complexes, [CuBrL] (1) and [CuL(CH3COO)] (2), where L is the deprotonated form of the Schiff base 5-bromo-2-((2-diethylaminoethylimino)methyl)phenol (HL), are prepared. The Schiff base and complexes are characterized by IR and UV spectra. In addition, the free Schiff base is characterized by 1H NMR spectrum. Structures of the complexes are further confirmed by single crystal X-ray determination. The Cu atoms in the complexes are in square planar coordination. The Schiff base ligand coordinates to the Cu atoms through phenolate oxygen, imino nitrogen and amino nitrogen. The bromide and acetate anions in the complexes furnish the square planar coordination. Catalytic property for epoxidation of styrene by the complexes is studied.
期刊介绍：
Journal is an interdisciplinary publication covering all aspects of structural chemistry, including the theory of molecular structure and chemical bond; the use of physical methods to study the electronic and spatial structure of chemical species; structural features of liquids, solutions, surfaces, supramolecular systems, nano- and solid materials; and the crystal structure of solids.
