Opis

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.

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
