TRIMETHYL(PHENYLSELENO)SILANE Chemical Properties,Usage,Production

Chemical Properties

clear yellow liquid

Physical properties

bp 92–93 °C/5 mmHg.

Uses

Phenyl Trimethylsilyl Selenide is widely used in synthesis of benzeneselenol; introduction of the phenylseleno function into a variety of oxygen-containing compounds.

Uses

Selenating reagent.

Preparation

Phenyl Trimethylsilyl Selenide is conveniently prepared by the reduction of diphenyl diselenide with sodium in THF, followed by silylation of thus formed PhSeNa with chlorotrimethylsilane. In a small scale reaction, silylation of PhSeLi, which can be prepared in situ from metallic selenium and phenyllithium in THF, is alternatively utilized.
