Abstract

Abstract: Stable carbanions react with diaryl disulfides in aqueous solution by a direct displacement (SN2) reaction to yield an arylthiol anion and the corresponding sulfide as products. The reaction of 1, 3-dicarbonyI carbanions with 5, 5'-dithiobis (2-nitrobenzoic acid) is characterized by a Brtlnsted pc value of 0.5. Nitroalkane carbanions react 102-104 slower than 1, 3-dicarbonyl carbanions of the same pK and are correlated by a Br~ nsted & of ...
