S-Alkyl, S-aryl, and S-vinyl thiosulfate sodium salts (Bunte salts), which can readily be prepared from sodium thiosulfate, react with Grignard reagents to give sulfides in good yields. The reaction is amenable to a broad structural array of Bunte salts and Grignard reagents. Importantly, this route to sulfides avoids the use of malodorous thiol starting materials or byproducts.
