WebIn organic chemistry, the oxy-Cope rearrangement is a chemical reaction.It involves reorganization of the skeleton of certain unsaturated alcohols. It is a variation of the Cope rearrangement in which 1,5-dien-3-ols are converted to unsaturated carbonyl compounds by a mechanism typical for such a [3,3]-sigmatropic rearrangement.. The reaction is highly … WebThe reaction mechanism proposed in the original Barton publication is outlined as follows: The hydrazone is oxidized by iodine into a diazo intermediate. In the next step, iodine reacts as an electrophile; displacement of nitrogen then generates an iodocarbonium ion.
