Abstract

The conversion of renewable biomass into sustainable feedstock for platform chemicals has attracted increased attention due to today’s high energy demand for sustainability. Highly oxygenated biomass feedstock requires selective processes for deoxygenation to occur in order to produce platform chemicals. The deoxydehydration (DODH) reaction converts vicinal diols into olefins by employing a metal catalyst and a variety of reductants along with the biomass-derived substrate. In this project, we report the DODH of styrene diol into styrene (up to 34 %) by implementing a specific oxo-molybdenum catalyst and triphenylphosphine as the reductant in a variety of solvents at 170 C. Examination of DODH reaction profiles by NMR spectroscopy indicates that the reaction is dependent upon the polarity of the solvent. The nature of the pendant group in the auxiliary ligand was found to influence reactivity.
