New oxidative transformations of alkenes and alkynes under the action of diacetoxyiodobenzene

Treatment of alkenes and alkynes with diacetoxyiodobenzene activated by mineral and organic acids predominantly results in oxidative rearrangement. 1,4-Diphenylbutadiene in MeOH gives 3,4-dimethoxy-1,4-diphenylbut-1-ene.

Oxidative Rearrangement of α-Benzylideneketones with Thallium(III) Nitrate in Methanol

Sterically unhindered arylidene- and diarylideneacetones 1 or 2 having electron releasing aryl groups yielded with thallium(III) nitrate in methanol β-ketoacetals 3, 4 and 5, respectively.Electronegatively substituted 1f and sterically hindered 1g and 1h gave the 4-arylcrotonic esters 7 and by-products, while 1,3-dibenzylidenacetone (2a) yielded besides the expected products also the branched acetal esters 13a and 13b.Formation of the anomalous products 7 and 13 can be rationalized assuming a common cyclopropanone type intermediate.
