METALLATION AND FUNCTIONALIZATION OF o-SULFONYLDI- AND o-SULFONYLTRIARYLCARBINOLS. UNEXPECTEDLY FACILE CYCLIZATION OF TERT-BUTYL-SULFONYLCARBINOL INTO A SULTINE

Article abstract of DOI:10.1007/BF00963512

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
