Peroxidic complexes of vanadium, niobium and tantalum, used as reactants and as catalysts for olefins epoxidation and hydrocarbons hydroxylation

摘要

Peroxidic complexes of vanadium, niobium or tantalum, wherein the metal is linked to an oxygen molecule carrying two negative charges, are used either as reactants for the oxidation of olefinic substrates or hydrocarbons, or as hydrocarbons oxidation catalysts, particularly for converting olefinic compounds to epoxides or aliphatic or aromatic hydrocarbons to the corresponding alcohols or phenols.
