Tetra-n-butylammonium permanganate

A study of the addition of dilithium carboxylates to acyclic enones under conditions of kinetic control has revealed that the reaction is irreversible and that the intrinsic preference for [1,2] addition may be completely changed to [1,4] when large groups are present on the acid or adjacent to the ketone group. The acid-catalysed decomposition of a-hydroperoxy-ketones to acids and ketones has been studied in detail in some cases, yields of acids can be excellent. 1,3-Dioxolans can be converted into the corresponding carboxylic acids by oxidative bromination followed by reduction with zinc under various conditions (Scheme 2).

Triazolines have been aromatized in good yield under two-phase conditions using potassium permanganate in the presence of tetra-n-butylammonium chloride [49].
