Baeyer-Villiger Oxidation of Ketones Catalyzed by Platinum(II) Lewis Acid Complexes Containing Coordinated Electron-poor Fluorinated Diphosphines

New hydroxo-bridged platinum(II) complexes of the type [P(μ-OH)(P-P)]2[BF4]2, containing fluorinated diphosphines, are used in the Baeyer−Villiger oxidation of 2-methylcyclohexanone using 35% hydrogen peroxide as oxidant. IR data of the isocyanide group in complexes of the type [PtCl(CN-2,6-(CH3)2C6H3)(P-P)][BF4] have allowed us to investigate the Lewis acidity of the complexes. A correlation is found between the electrophilicity of the metal center and the catalytic activity of complexes in the Baeyer−Villiger oxidation of ketones.
