A novel metallic samarium promoted reduction of sodium alkyl thiosulfates in the absence of an activating agent occurs to afford the corresponding disulfides with good yields in water at 90°C.

A newly developed C–S bond formation process via acid-catalyzed thia-Michael addition has been demonstrated. The protocol, in which Buntesalts generated from odorless and inexpensive sodium thiosulfate and organic halides are used as the thiol precursors, provides an efficient approach for the synthesis of β-sulfido carbonyl compounds.

withdrawing character of para substituents of α-halogeno toluenes in the preparation of unsymmetrical disulfides using the Bunte salt method. The use of DMSO as a reaction solvent permits not only to dissociate the sodium salt, but also to synthesise unsymmetrical disulfides from compounds which are inadequate using conventional methods.
