The reactions of the olefins Ph2ArC·CHCH2(Ar = Ph and p-anisyl) with leadtetra-acetate and with iodine in the presence of silver acetate have been studied and conclusions have been reached about the mechanisms of oxidation (which, in all cases, is accompanied by rearrangement). In particular, evidence is adduced that a carbonium ion is formed at each of two phases of the reaction with each reagent
