Diphenyl diselenide is the chemical compound with the formula (C 6 H 5) 2 Se 2, abbreviated Ph 2 Se 2. This yellow-coloured solid is the oxidized derivative of benzeneselenol . It is used as a source of the PhSe unit in organic synthesis .
Benzeneselenol (also called selenophenol or PhSeH) is more acidic (pK a 5.9) than thiophenol (pK a 6.5) and also oxidizes more readily to the diselenide. Selenophenol is prepared by reduction of diphenyldiselenide. [7] Diselenides (R−Se−Se−R) are the selenium equivalents of peroxides and disulfides. They are useful shelf-stable precursors ...
Diphenyl diselenide and several benzylic selenides have been explored by Kwon et al. as photoiniferters in polymerization of styrene and methyl methacrylate. Their mechanism of control over polymerization is proposed to be similar to the dithiuram disulfide iniferters.

A December 2024 study in the journal Chemosphere incorrectly calculated the amount of potentially toxic flame retardants that could be present in some black plastic household products such as ...
More so than thiophenol, benzeneselenol is easily oxidized by air. The facility of this reaction reflects the weakness of the Se-H bond, bond dissociation energy of which is estimated to be between 67 and 74 kcal/mol. [1] In contrast, the S-H BDE for thiophenol is near 80 kcal/mol. [3] The product is diphenyl diselenide as shown in this idealized equation:
