Palladium-catalysed Hydrosulfination: Synthesis of Sulfonic Acids and S-Alkyl Alkanethiosulfonates from Alkenes, Sulfur Dioxide and Hydrogen
Keim, Wilhelm,Herwig, Juergen
, p. 1592 (1993)
S-Alkyl alkanethiosulfonates and sulfonic acids can easily be synthesized from sulfur dioxide, alkenes, hydrogen and a cationic palladium(II)-diphosphine complex like 2 1 , at temperatures above the ceiling temperature of the SO2-alkene copolymer.

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 under solvent-free conditions or with a minimum amount of solvent assisted by magnetic stirring, ultrasound irradiation and microwave irradiation. Ultrasound irradiation has good effects on the synthesis of sterically hindered thiosulfonate S-esters in solvent-free media as well as in a minimum amount of anhydrous diethyl ether.
