Abstract

Kinetics of formation and oxidation of hydroxyl the η 3 -аllil complexes of a palladium with isoprene and sorbic acid in water and water - аcetonitril solutions in presence of chloride - ions are investigated. Presence of balance between Na2PdCl4 and allil complex in reactions of formation is established. Research of reactivity of η 3 -аllil complexes was done in reactions of oxidation by para - benzquinone in presence of DС1. In specified conditions protodemetallation reaction of allil complex proceeds simultaneously with oxidation reaction. It is established that in reaction system direct oxidation of diene-derivative products with formation of products of various structure proceeds, as well as direct oxidation of η 3 -аllil complex. Kinetic and thermodynamic characteristics of researched reactions are determined.
