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.

groups on the alkyl group were transformed efficiently into the corresponding carbonylcompounds, particularly primary alkyl aryl selenides in good yields, by a simple photolysis in the presence of air or oxygen. This transformation can be conducted without protection of functional groups. The yield of carbonylcompounds was much affected by the solvent viscosity, reaction temperature, concentration
