Na2SeSO3, which can be generated in situ by the reaction of Na2SO3 with Se power, was found to be an odorless reagent for the selenenylation of alkyl halides RX (R = Bu, cyclohexyl, 3-fluorobenzyl, etc.; X = Cl, Br) to produce dialkyl diselenides RSeSeR. By using aqueous EtOH as the solvent and avoiding the generation of a malodorous selenol intermediate, the selenylation reaction with Na2SeSO3 is much more environmentally friendly than conventional methods. Owing to the cheap and abundant starting materials and selenium reagents, the novel synthetic method reduces the production costs of dialkyl diselenides as organoselenium catalysts, thereby advancing practical applications of organoselenium-catalysis technologies. In the experiment, the researchers used 3-Chlorobenzylchloride(cas: 620-20-2Quality Control of 3-Chlorobenzylchloride)
3-Chlorobenzylchloride(cas: 620-20-2) has been used in the reaction of 3-methoxybenzyl chloride and ethyl 4-bromobenzoate in pure water, using zinc dust and a Pd catalyst.Quality Control of 3-Chlorobenzylchloride
