摘要

The high-yielding synthesis of diphenolic acid (DPA) using Brønsted acidic ionic liquids (BAILs) has been demonstrated in this study. Importantly, p, p′-DPA was obtained as the preferential product over o, p′-DPA with an isomer ratio over 100. Moreover, diphenolic esters were also prepared in high yield through a one-pot method.
