sodium sulfinates, and aldehydes under mild reaction conditions is described. This transformation provides a direct synthetic approach to 2-sulfonyl benzylalcohol derivatives, which could be rapidly converted to diverse arylsulfur compounds via the transformation of the corresponding hydroxyl groups. Various aryne precursors, sodium arenesulfinates, and aromaticaldehydes can be effectively converted
Diaryl sulfoxidesbearing ortho-sulfur substituents react readily with Grignard reagents on the sulfur atom to produce the corresponding phenyl Grignard reagents bearing ortho-sulfur functional group. Furthermore, thianthrene monooxide was found to react with alkyl Grignard reagents affording o,o′-bis-Grignard reagent of diphenyl sulfide which was converted easily to Martin’s sulfurane.

The lithiation of o-sulfonyltriphenylcarbinols proceeds in the ortho position relative to the sulfonyl group, as indicated by formation of the corresponding carboxylic acids upon the action of CO2. Unusual facility was found for the loss of the tert-butyl group in 2-(tert-butylsulfonyl)-3-diphenylhydroxymethyl-benzoic acid in acid media to give the corresponding sultine.
