Sodium Selenosulfate from Sodium Sulfite and Selenium Powder: An Odorless Selenylating Reagent for Alkyl Halides to Produce Dialkyl Diselenide Catalysts

Na 2 SeSO 3, which can be generated in situ by the reaction of Na 2 SO 3 with Se power, was found to be an odorless reagent for the selenenylation of alkyl halides to produce dialkyl diselenides. These products have been recently shown to be good catalysts for the Baeyer-Villiger oxidation of carbonyl compounds, for the selective oxidation of alkenes, or for the oxidative deoximation of oximes. By using aqueous EtOH as the solvent and avoiding the generation of a malodourous selenol intermediate, the selenylation reaction with Na 2 SeSO 3 is much more environmentally friendly than conventional methods. Owing to the cheap and abundant starting materials and selenium reagents, our novel synthetic method reduces the production costs of dialkyl diselenides as organoselenium catalysts, thereby advancing practical applications of organoselenium-catalysis technologies.

Electrochemical synthesis of organochalcogenides in aqueous medium

The electrochemical preparation of telluride, selenide and sulfide ions was carried out in NaOH aqueous solution, using a two compartment cell. Organochalcogenides were prepared from halogenated compounds in a two-step procedure. The monochalcogenides were obtained as the major products in good yields.

Improved method for the synthesis of organic diselenides from organic halides under atmospheric pressure

An improved approach to the synthesis of organic diselenides is reported. The process involves the reaction of organic halides with selenium, carbon monoxide, and water under atmospheric pressure in the presence of an inorganic base, sodium hydroxide, to afford organic diselenides in good yields.
