A palladium(II) complex of a new iminophosphine ligand derived from diethylenetriamine and 2-(diphenylphosphino)benzaldehyde
摘要:
The mononuclear complexes [Pd(oPdien)]X-2 {oPdien = N-(2-diphenylphosphinobenzylidene)diethylenetriamine: (4a) X-2 = [ZnCl4](2-); (4b) X = [PF6](-); (4c) X = Cl-} are described. Complex 4a formed in high yield when [Pd(oPCHO)(2)Cl-2][oPCHO = 2-(diphenylphosphino)benzaldehyde] (1) and [Zn(dien)Cl-2] (2) were reacted together in an unsuccessful attempt to template formation of a bimetallic iminophosphine-bridged complex. The X-ray crystal structure of 4b has been determined. The ligand oPdien is the first iminophosphine derived from dien and has been isolated and used to prepare 4c. (C) 2000 Elsevier Science S.A.
