Synthesis of Dibenzylic Diselenides from Elemental Selenium and Benzylic Quaternary Ammonium Salts

Abstract: Substituted dibenzyl diselenides are synthesized in good yields (74–91 %) by SN2 nucleophilic substitution of benzylic trimethylammonium salts and diselenide dianion (Se2?), in situ generated from elemental selenium, under

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.

Alternative Protocol for the Synthesis of Symmetrical Dibenzyl Diselenides and Disulfides

A one-pot protocol for the preparation of symmetrical dibenzyl diselenides and disulfides from the corresponding benzyl alcohols employing NaBH2Se3 and NaBH2S3 as selenium-transfer and sulfur-transfer reagent, respectively, is described. Structurally diverse substituted benzyl alcohols afforded the corresponding diselenides and disulfides in good to excellent yields. The protocol is simple and mild, and the products were obtained within a short reaction time.
