Oxidative Synthesis of α,β-Unsaturated Ketone from α-Iodo Ketone Using Peracid

Oxidation of α-iodo ketone in CH2Cl2 using m-chloro­perbenzoic acid yields α,β-unsaturated ketone by β-H elimination in good yield. This reaction affords a new and convenient synthetic method for α,β-unsaturated ketone from α-iodo ketone.
