Synthesis, characterization and Baeyer–Villiger oxidation of ketones by the bis-cationic platinum(II) complex [Pt(μ-OH)(Pom-Pom)]2[BF4]2 [Pom-Pom = (OMe)2PCH2CH2P(OMe)2]

The synthesis and spectroscopic characterization of the new hydroxo-bridged platinum(II) complex [P(μ-OH)(Pom-Pom)]2[BF4]2 (3) containing the electron-poor P–P ligand 1,2-bis(dimethoxyphosphino)ethane, (OMe)2PCH2CH2P(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/H2O biphasic system. The catalytic activity and the Lewis acidity of the complex (3) has been compared to other Pt(II) complexes previously investigated.
