Abstract

A route to renewable phthalic anhydride (2-benzofuran-1, 3-dione) from biomass-derived furan and maleic anhydride (furan-2, 5-dione) is investigated. Furan and maleic anhydride were converted to phthalic anhydride in two reaction steps: Diels–Alder cycloaddition followed by dehydration. Excellent yields for the Diels–Alder reaction between furan and maleic-anhydride were obtained at room temperature and solvent-free conditions (SFC) ...
