clear yellow liquid | [Uses]
Benzeneselenol may be 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. | [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.
