Oxidation of α-iodo ketone in CH 2 Cl 2 using m-chloroperbenzoic acid yields α,β-unsaturatedketone by β-H elimination in good yield. This reaction affords a new and convenient synthetic method for α,β-unsaturatedketone from u-iodo ketone.

Enol silanes derived from aldehydes and ketones are readily converted to the corresponding α,β-unsaturated carbonyl compounds by 10% Pd(OAc)2 in the presence of one atmosphere of oxygen in DMSO as the solvent.
