Abstract

An ionic solid catalyst by pairing Keggin polyoxometalate-anions with Pd^II-coordinated nitrile-tethered ionic liquid cations was synthesized, characterized, and tested for aerobic oxidation of benzene to biphenyl. A unique heterogeneous intramolecular electron transfer mechanism is proposed to understand its high activity.
