Beschreibung

General description

Diphenyl diselenide (Ph₂Se₂) is an organoselenium compound. Its crystalline structure, toxicokinetic properties,[1] antioxidant and anti-inflammatory activities have been investigated.[2] Its ability to reverse the oxidative brain damage and mitochondrial dysfunction induced by acetaminophen has been studied in mice.[3] It reacts with thallium (Tl) to form TI (SePh). It participates in a four-component radical coupling to form substituted cyclopentanes.

Application

Diphenyl diselenide (Ph₂Se₂) may be used in the following studies:

• methoxyselenenylation of alkenes
• dihydroxylation of double bonds
• hydrothiolation of terminal alkynes

It may be used in the synthesis of the following:

• unsymmetrical diorganyl selenides
• 1-(phenylselenomethyl)vinyl selenides
• allylic phenyl selenides
