Naturally occurring organic acids are reported to be highly efficient promoters of the Beckmann rearrangement. Citric, oxalic, tartaric, malic, succinic, malonic, and fumaric acids efficiently promote the Beckmann rearrangement under solvent-free conditions and thermal and microwave irradiation. Tar
Beckmann rearrangements of benzaldehyde and 2-hydroxyacetophenone were largely improved by performing solvent-free reactions in the presence of one equivalent of anhydrous zinc chloride. When compared to conventional heating under the same conditions, yields are significantly enhanced under microwav
