Ol-Sulfony' carbanions of structure R-SO,-T (Rl)(R2) ACIDS Mass. 02138 can be generated from optically active precursors R-S02-C (Rl)(R2)(Y) in hydroxylic media and protonated to give optically active products, R-S02-CH(Rl)(R2), with high stereospecificity. This remarkable

Primary and secondary a-sulfonyl-carbanions react with chlorotolaenetricarbonylchromium complexes to give, after CF3 C 0 2 H treatment, aryl-sulfones via ipso, tine and tele nucleophilic aromatic substitution of chloride.
