Alkenes were converted into α,β-unsaturated carbonyl compounds using excess of tert.butylhydroperoxide and catalytic amounts of chromiumVI oxide at room temperature. Fair yields and conversions were obtained from Δ5-steroids while allylicoxidation of acyclic alkenes was less efficient. Epoxidation of the double bond, sometimes observed, remained a minor reaction pathway.
