Catalytic activity of bimetallic catalyst Pd(II)(PVP)-Cu(II)(PVP) in oxidation of octene-1

Abstract

The oxidation of octene-1 in aqueous organic solutions in the presence of bimetallic catalytic system (Pd (II)(PVP)-Cu(II)(PVP) (PVP - polyvinylpyrrolidone)) at 60–80 °C under mild conditions was studied. Kinetics, products and optimal reaction conditions were studied by the methods of kinetics, volumometry, gas chromatography and mass spectrometry. It have been found the optimal composition of the catalyst system [Pd(II)(PVP)]:[Cu(II)(PVP)]:[C8H16] = 1:(5–10):22. The maximum rate of oxygen absoprtion in most experiments was observed at 80 °C. Dimethylsulfoxide (DMSO) was used as solvent. The main reaction product was octanone-2 (34–70%). The maximum number of TONs was 236 mol of product/(mol Cat), and the maximum number of TOFs was 71 mol of product/ (mol of Cat⋅h).
