A mixture of chloral hydrate () and hydrogenperoxide () was developed as a novel effective epoxidation reagent. Its efficacy was tested with steroid structures. It is moderate oxident superior to peracids and other hydrogenperoxide / catalyst combinations due to its higher regio- and stereoselectivity. Allylic and homoallylic alcohols () are more rapidly epoxidized by neighbouring group part participation
