Bunte salt

In organosulfur chemistry, a Bunte salt is an archaic name for salts with the formula RSSO3–Na+. They are also called S-alkylthiosulfates or S-arylthiosulfates. These compounds are typically derived from alkylation on the pendant sulfur of sodium thiosulfate: In organosulfur chemistry, a Bunte salt is an archaic name for salts with the formula RSSO3–Na+. They are also called S-alkylthiosulfates or S-arylthiosulfates. These compounds are typically derived from alkylation on the pendant sulfur of sodium thiosulfate: They have been used as intermediates in the synthesis of thiols. They are also used to generate unsymmetrical disulfides: According to X-ray crystallography, they adopt the expected structure with tetrahedral S(VI), an S-S single bond, and three S=O double bonds.
