Combining the ability of ionic liquids to dissolve biomass with the reactivity of metalloporphyrin oxidation catalysts could overcome many of the challenges to lignin utilization. Ionic liquids have shown promise as solvents for the dissolution of cellulose and lignin and therefore have the potential to assist catalysts as they breakdown the components of biomass and in separation of biomass components.  We have synthesized and studied the reactivity of ionic liquid-tagged iron and manganese porphyrins for their reactivity in a range of ionic liquids which we have found to solubilize lignin.  Our results from a comparison study of the catalytic activity of purchased metalloporphyrins versus synthesized ionic liquid-tagged metalloporphyrins towards simple lignin model compounds will be presented.
