Abstract

The Friedel–Crafts acylation of activated and polycyclic aromatics is efficiently catalyzed by bismuth (III) chloride which is generated in situ from bismuth (III) oxychloride, a water insensitive and eco-friendly material. Bismuth (III) oxychloride is easily recovered in near quantitative yields after an aqueous work-up.
