The selective removal of oxygen from biomass feedstocks, such as carbohydrates, sugar alcohols and glycerol, is a challenge that must be met in order to produce value-added chemicals and fuels.  A number of groups, including our own, have recently described systems for the deoxydehydration (DODH) of polyols to olefins, employing various reductants and oxo-rhenium catalysts.  We have now discovered that inexpensive oxo-vanadium and oxo-molybdenum complexes are also effective for the DODH of glycols with sulfite or secondary alcohols as reductants.  The activity, selectivity, substrate scope, and catalyst structure-activity features of these catalytic systems will be presented.
