DIPHENYL SELENIDE Usage And Synthesis
Chemical Propertiesclear yellow to red-brown liquid
UsesDiphenyl selenide is used for anti-selective Michael addition of thiols and their analogs to nitro-olefins.
General DescriptionDiphenyl selenide is an organoselenium compound. Its standard enthalpies of combustion, formation and the mean bond-dissociation energy have been calculated. Its potential as a neutral carrier to develop silver-selective membrane electrode has been investigated. Diphenyl selenide undergoes oxidation to form selenoxides on treating with N-bromosuccinimide followed by alkaline hydrolysis.
Safety ProfilePoison by ingestion. When heated to decomposition it emits toxic fumes of Se. See also SELENIUM COMPOUNDS
