Oxidative Dihydroxylation of Alicyclic Unsaturated Hydrocarbons with Vinyl- and Norbornene Fragments in Pseudohomogenic System

摘要

Oxidation of alicyclic unsaturated hydrocarbons (4-vinylcyclohexene, 5-vinylnorbornene, 5-cyclo-hexenylnorbornene, and 5-vinylbicyclooctene) with 30% hydrogen peroxide solutions and percarbamide is studied. Reaction was carried out at 40-70°C in the presence of heterogenized peroxocomplex compounds of molybdenum and tungsten formed "in situ" in the reaction of metal oxohalides with H3PO4, nano-dimensional particles of carbon material, and hydrogen peroxide. Main oxidation products of alicyclic diene hydro-carbons are the corresponding unsaturated epoxides and diols. Depending on the reaction condition their ratio varies in a wide range.
