Abstract

Cyclopropyl malonoyl peroxide, which can be prepared in a single step from the commercially available diacid, enables an effective dihydroxylation of alkenes in the presence of water at 40°C. Alkaline hydrolysis of the resulting monoester leads to the corresponding diol. With 1,2-disubstituted alkenes, the reaction proceeds with syn selectivity.
