Changing solvent polarity (considered in terms of dielectric permittivity ? is an easy experimental way for tuning the reactivity of electrogenerated cation radicals of alkyl aromatic selenoethers. First-order cleavage of SeC3 bond is favored in polar media, whereas bimolecular cation radical disproportionation becomes the main reaction in low-polar solvents. The key element of this dichotomy is the dielectric adjustment of specific transannular interactions between Se and CO group in the cation radicals. A series of alkyl arylselenides with pending carboxy or acetamido substituents was studied by cyclic voltammetry, IR spectroscopy and DFT calculation in binary solvents covering the span of polarity 8 2Se 2.

Diphenyl diselenide was found to be readily converted into benzeneselenenyl-m-nitrobenzenesulfonate (PhSeOSO2C6H4NO2-m) by treating with m-nitrobenzenesulfonyl peroxide.When the selenenyl sulfonate thus formed was allowed to react in situ with olefins, such as cyclohexene, 1-octene, or styrene, in the presence of various nucleophiles, the adducts of benzeneselenenyl group and a nucleophile were obtained.As the nucleophiles water, methanol, acetic acid, phenol, and anisole could be employed; oxyselenenylated : R=H, Me, Ac, and Ph) and arylselenenylated : R=H and Me) adducts were afforded.Phenol gave oxyselenenylated products in cyclohexene or 1-octene and arylselenenylated products in styrene.Efficient intramolecular cyclizations of unsaturated alcohols and carboxylic acids were similarly performed by the selenenyl sulfonate to afford corresponding benzeneselenenylated cyclic ethers and lactones.The selenenyl sulfonate was also found to be a highly reactive benzeneselenenylating reagent for aromatic rings, such as anisole, phenol, acetanilide, toluene, and benzene.
