The sulfone functional group has a strong capacity to direct the asymmetric transfer hydrogenation (ATH) of ketones in the presence of [(arene)Ru(TsDPEN)H] complexes by adopting a position distal to the η6-arene ring. This preference provides a
Synthesis of 2-acetylenic carboxylic acids, 1-sulfinyl and 1-sulfonyl- 2-ketones from 2-acetylenic phenyl sulfides

Monochlorination at the 1-position with sulfuryl chloride, followed by methanolysis converted 2-acetylenic phenyl sulfides into 1-methoxy-2- acetylenic phenyl sulfides. Oxidation with chromic acid gave 2-acetylenic carboxylic acids. Oxidation of 2-acetylenic phenyl sulfides with Oxone and hydrogen peroxide in acetic acid gave the corresponding sulfoxides and sulfones respectively. Diethylamine addition to the triple bond produced enamines which were hydrolyzed with aqueous hydrochloric acid to the corresponding 1-sulfinyl and 1-sulfonyl-2-ketones.
