Vanadyl pyrophosphate catalysts displayed a variety of catalytic functionalities in the oxidation of C4 molecules. Hydrocarbons were isomerized and dehydrogenated to olefins, as well as being oxidized. Branched hydrocarbons did not desorb from the pyrophosphate catalyst surface and appeared to undergo total oxidation. Alcohols were dehydrated to olefins and also were isomerized. 1,4 Butanediol was oxidized to maleic anhydride with very high selectivity. An active site for the initial CH bond activation at a cis-(su)peroxo oxovanadium(V) dimer site is proposed.
