Abstract

Stable and non-hygroscopic aluminum dodecatungstophosphate (AlPW₁₂O₄₀), which is prepared easily from cheap and commercially available compounds, is an effective catalyst for Friedel-Crafts acylation reactions using carboxylic acids, acetic anhydride and benzoyl chloride in the absence of solvent under mild reaction conditions.
