The Uses of Diphenyl diselenide

Diphenyl diselenide is used in the methoxyselenenylation of alkenes, dihydroxylation of double bonds, hydrothiolation of terminal alkynes. It is used in the synthesis of the unsymmetrical diorganyl selenides, 1-(phenylselenomethyl)vinyl selenides, allylic phenyl selenides.

General Description

Diphenyl diselenide (Ph2Se2) is an organoselenium compound. Its crystalline structure, toxicokinetic properties, antioxidant and anti-inflammatory activities have been investigated. Its ability to reverse the oxidative brain damage and mitochondrial dysfunction induced by acetaminophen has been studied in mice. It reacts with thallium (Tl) to form TI (SePh). It participates in a four-component radical coupling to form substituted cyclopentanes.

Biochem/physiol Actions

Diphenyl diselenide inhibits δ-aminolevulinate dehydratase (δ-ALA-D) from brain, liver and kidney in vitro.

Purification Methods

Crystallise it twice from hexane [Kice & Purkiss J Org Chem 52 3448 1987]. [Beilstein 6 IV 1781.]
