摘要
The synthesis of new cyclopalladated compounds by reaction between palladium acetate and the potentially tridentate imines 4-ClC6H4CH=N(CH2)(n)NMe2 (n = 2, 3) in acetic acid is described. The experimental data suggest a dinuclear structure for the complexes. with a bridging C-N-N' ligand. H-1 NMR spectra of these complexes in CD3COOD solution, indicate the existence of three different species in equilibrium. (C) 2002 Elsevier Science B.V. All rights reserved.
