The utility of zinc selenolates for effecting nucleophilic cleavage of simple lactones and esters has been investigated. When zinc selenolate generated via Zn/AlCl3-promoted cleavage of diselenides was reacted with simple lactones and esters, efficient nucleophilic alkyl–oxygenbondcleavage proceeded generating the corresponding carboxylic acids in moderate to excellent yields.

efficient one-pot synthesis of γ-arylselenenyl ketones, acids, and nitriles is presented. The method uses Zn/AlCl 3 -promoted cleavage of diselenides and subsequent ring-opening of mono-activated cyclopropanes.
