PHENYLSELENOL Usage And Synthesis

Chemical Properties

clear yellow liquid

Uses

It is applied for reactions of phenylselenol and its anion. Benzeneselenol can used as starting reagent in the synthesis of monoseleno-substituted 1,3-dienes. It may be used in the synthesis of cationic chalcogenolato-bridged diruthenium complexes.

General Description

Benzeneselenol is an aryl selenol. Diphenyl diselenide-promoted radical addition of benzeneselenol to inactivated acetylenes upon irradiation through Pyrex with a tungsten lamp has been reported. Catalysis of stannane-mediated radical chain reactions by benzeneselenol, generated in situ by reduction of diphenyl diselenide with tributyltin hydride, has been reported.

Purification Methods

Dissolve it in aqueous N NaOH, acidify this with conc HCl and extract with Et2O, dry over CaCl2, filter, evaporate on a steam bath and distil the residue from a Claisen flask or through a short column collecting the middle fraction, and seal immediately in a glass vial, otherwise the colourless liquid becomes yellow. The alkali insoluble materials consist of diphenylselenide (b 167o/16mm) and diphenyldiselenide, m 63o (from EtOH). TOXIC, use rubber gloves. It has a foul odour.
