Abstract
Using the enantiopure phosphinoalcohol ligand (P,OH) ( 1) [(P,OH)=[(1 S),(2 S),(4 R)-1-OH-1-Me-2-PPh 2-4-C(Me)CH 2- c-C 6H 7], the stable Pd(II) complexes [(dmba)Pd( P,OH)Cl] ( 2) (dmba= o-C 6H 4CH 2NMe 2), [(dmba)Pd( P, OH)]PF 6 ( 3) and [(dmba)Pd( P, O)] ( 4) have been prepared. Conductivity and NMR measurements showed that complex 2 gives rise to a solvent-dependent equilibrium in solution between the neutral and the cationic species [(dmba)Pd( P,OH)Cl] ( 2a) and [(dmba)Pd( P, OH)]Cl ( 2b), respectively. The crystal structures of 2b and [(dmba)Pd( P, OH)]PF 6 ( 3) have been determined by X-ray diffraction. In the solid state, both cationic complexes display chelating behaviour for the P,OH ligand.
