CATIONIC PD(II) COMPLEXES CATALYTICALLY ACTIVE IN THE OXIDATION OF OLEFINS : MECHANISMS OF THE FORMATION IN WATER -ACETONITRILE -CHLORIC ACID MEDIUM

The catalytic system Pd (OAc)2-HClO4--CH3CN (AN)-H2O of olefins oxidation was studied. Information about the ways of forming catalytic active cationic palladium complexes was detected. Analysis of the electron spectroscopy data shows the probability of existence complexes [Pd(AN)(H2O)3]2+ (λmax = 360-365 nm), [Pd(AN)2(H2O)2]2+ (λmax = 335-345 nm) in catalytic system. The preparation method of stable and sufficient active catalytic system for obtaining reproducible kinetic data was designed.
