Abstract The reactions of the title compound, Me2Sn(S-SO3Na · H2O)2, with alkyliodides and trimethyltin chloride in an aqueous medium, as well as with dibenzo-18-crown-6 (DB-18-C-6) in acetone have been studied. The iodides RI (R = Me, Et) attack both of the tin—sulfur bonds to give dimethyltin diiodide and the respective disulfides, R2S2. Trimethyltin chloride enters an exchange reaction which involves sodium ions and affords Me2Sn(S-SO3SnMe3)2 as the reaction intermediate; the latter decomposes to ultimately give trimethyltin sulfate, dimethyltin thiosulfite, and elemental sulfur. An ionic complex, [Me2Sn(S-SO3)2]2 2−[Na(DB-18-C-6)(Me2CO)]+[Na(DB-18-C-6)(Me2CO)(H2O)]+, soluble in acetone and methylene chloride has been also synthesized, and its structure has been determined by means of X-ray techniques.
