GRAPHICAL ABSTRACT Abstract Amberlyst A-26, Mg-Al hydrotalcite, potassium fluoride absorbed on alumina, triethylamine and pyridine have been tested as base catalysts and reagents for the reaction of sulfonyl chlorides with thiols to prepare thiosulfonate S-esters. The reactions were performed undersolvent-freeconditions or with a minimum amount of solvent assisted by magnetic stirring, ultrasound
