Synthesis, characterization and coordination chemistry of (pyrazolylphosphinite)palladium(II) complexes

Abstract

Pyrazolylethylphosphinite compounds, L1 (2-(3,5-dimethyl-1H-pyrazol-1-yl)ethyldiphenlyphosphinite) and L2 (2-(3,5-di-tert-butyl-1H-pyrazol-yl)ethyldiphenylphosphinite) were reacted with the palladium(II) precursors [PdCl(CH3)(COD)] and [PdCl2(NCCH3)2] resulted in the formation of five novel complexes, produced from disproportionation reaction and have very interesting coordination chemistry. The results further emphasize the coordination versatility of pyrazolylphosphinite ligands towards palladium(II) metal centres.
