text: In organosulfur chemistry, a Bunte salt is an archaic name for salts with the formula RSSONa.  They are also called S-alkylthiosulfates or S-arylthiosulfates.  These compounds are typically derived from alkylation on the pendant sulfur of sodium thiosulfate:
  :RX  +  NaSO   →  Na[OSR]  +  NaX
  They have been used as intermediates in the synthesis of thiols.  They are also used to generate unsymmetrical disulfides:
  :Na[OSR]  +  NaSR   →   RSSR  +  NaSO
  According to X-ray crystallography, they adopt the expected structure with tetrahedral sulfur(VI) atom, a sulfur-sulfur single bond, and three equivalent sulfur-oxygen bonds.
