Abstract

An efficient and cost-effective cis-dihydroxylation reaction of acrylate derivatives in acetone with an imidazolium salt as catalyst and KMnO₄ as the oxidant provides dihydroxylated products without overoxidation. This non-aqueous protocol is highly suitable for the large-scale preparation of cis-dihydroxylated compounds.
