Abstract

The complex [PdCl2(bdtp)], in presence of AgBF4 or NaBF4, reacts with triphenylphosphine, pyridine, cyanide, thiocyanate and azide ligands, leading to the formation of complexes cis-[Pd(bdtp)(PPh 3)2](BF4)2 [1](BF4) 2, [Pd(bdtp)(py)2](BF4)2 [2](BF 4)2, [Pd(bdtp)(py)](BF4)2 [3](BF4)2, [Pd(CN)2(bdtp)] [4], and [Pd(X)(bdtp)](BF4) (X = SCN- [5](BF4), N3-[6](BF4)). However, the similar reaction of [PdCl 2(bdtp)] with AgBF4 or NaBF4 in presence of bipyridine, produces the displacement of the bdtp ligand yielding [PdCl 2(bpy)] complex. In this case a new synthetic route was then tried. Complex [Pd(bpy)2](BF4)2 reacts with bdtp ligand, to obtain [Pd(bpy)(bdtp)](BF4)2 [7](BF 4)2 complex. These complexes were characterised by elemental analysis, mass spectrometry, conductivity measurements, infrared and NMR spectroscopies. © 2010 Elsevier Ltd. All rights reserved.
