Synthesis of Diaryl Ketones Catalyzed by Al₂O₃‐ZrO₂/S₂O₈ ²⁻ Solid Superacid

Abstract

Abstract The acylation of a variety of aromatic compounds with benzoyl chloride or its derivatives and catalytic amounts of Al2O3–ZrO2/S2O8 2− solid superacid affords the corresponding diaryl ketones in good to excellent yields 75–93% at appropriate temperature.
