| Popis: | The synthesis and spectroscopic characterization of the new hydroxo-bridged platinum(II) complex [P(μ-OH)(Pom-Pom)] 2 [BF 4 ] 2 ( 3 ) containing the electron-poor P–P ligand 1,2-bis(dimethoxyphosphino)ethane, (OMe) 2 PCH 2 CH 2 P(OMe) 2 (Pom-Pom), is reported. This compound has been used in the Baeyer–Villiger oxidation of a series of cyclic ketones using 35% hydrogen peroxide as oxidant. The reactions were performed at 25 °C and at 70 °C in chlorinated solvent/H 2 O biphasic system. The catalytic activity and the Lewis acidity of the complex ( 3 ) has been compared to other Pt(II) complexes previously investigated. |
