✦ Synopsis

Several potassium selenocarboxylates

were synthesized in moderate to good yields by the direct reaction of acyl chlorides with potassium selenide. The potassium salts were readily oxidized with XeF 2 to give diacyl diselenides in quantitative yields. The structure of di(4-methoxybenzoyl) diselenide was established by X-ray diffraction analysis. Intramolecular interactions between the carbonyl oxygen and the selenium that is connected to the opposite carbonyl group were observed.
