In moving toward renewable, sustainable energy sources, biodiesel shows promise as an effective alternative for fossil fuels. However, a considerable amount of glycerol is generated during biodiesel production as a byproduct. The generation of glycerol from biodiesel is far exceeding the demand for this chemical. Methods to convert glycerol selectively into other chemical feedstocks is of significant interest. The iridium pincer complex, (NMe2)(POCOP)Ir(CO) ((NMe2)POCOP = κ3-4-NMe2-C6H2-2,6-[OP(tBu)2]2), was previously shown to catalyze the deoxygenation of glycerol to 1-propanol and 1,3-propanediol. The preparation and characterization of new (POCOP)Ir(CO) complexes with other substituents on the aryl backbone will be presented and the results of glycerol deoxygenation reaction with new catalysts will be compared to that of the dimethylamino substituted complex.
