Diselenide

Diselenides are covalent chemical compounds of the type R – Se – Se – R ′. If the organic radicals R and R 'are the same, it is a symmetrical diselenide. If the radicals R and R ′ are different, the diselenide is asymmetrical. Ionic (mostly inorganic) compounds that contain the diselenide ion ^- Se-Se ^- are also called diselenides, but represent a separate group of substances. Both groups of substances can be viewed as derivatives of the unstable diselane H ₂ Se ₂ . Diselenides are the selenium analogues of the disulfides .

synthesis

Symmetrical organic diselenides can be prepared by direct introduction of the diselen group into organic molecules or by oxidation of selenols . The autoxidation of selenols in air provides Diselenide:

Reactions

The reduction of organic diselenides produces selenols. Sodium is often used as a reducing agent .
