|Abstract: ||Some copper(I) complexes of the type [Cu(L)(PPh(3))(2)]X (1-4) [where L = 2-chloro-(5-trifluoromethyl-phenyl)-pyridine-2-ylethylene-amine; X = Cl(-), CN(-), ClO(4)(-) and BF(4)(-)] have been prepared by the condensation of 3-amino-4-chloro-benzotrifluoride with 2-acetylpyridine followed by the reaction with [Cu(MeCN)(2)(PPh(3))2]Cl, [Cu(MeCN)(2) (PPh(3))(2)]CN,[Cu(MeCN)(2)(PPh(3))(2)]ClO(4) and [Cu(MeCN)(2)(PPh(3))(2)]BF(4). All the complexes 1-4 were characterized on the basis of elemental analysis, IR, UV-visible and (1)H NMR spectral studies. The representative complex of the compound 3 has been characterized by single crystal X-ray diffraction which reveals that the central copper(I) ion assumes highly distorted tetrahedral geometry. All the complexes worked as effective catalyst for the amination of aryl halide. (C) 2011 Elsevier B.V. All rights reserved.|
