Ramberg-Backlund rearrangement mechanism

Based on extensive studies associated with the Ramberg-Backlund rearrangement s and its mechanism , including the treatment of thiirane oxides with bases, the following conclusions emerge ... [Pg.402]

Reactions of (145) with potassium permanganate, performic acid, aqueous lithium carbonate, and silver acetate in acetic acid are described. Treatment of the cyclopentadiene-methyl a-bromovinyl sulphone adduct with sodium methoxide in dimethyl sulphoxide gives (141) by the Ramberg-Backlund rearrangement, but in refluxing aqueous 2N sodium hydroxide (146) is also formed. Good evidence in the latter case is presented for a homolytic mechanism. With added isopropyl alcohol, in addition to (146), products are obtained by hydrogen-atom abstraction. [Pg.349]
