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.

Application

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.
