Reactions of alpha,beta-dinitroolefins with 1,2-ethanedithiol form five-membered ring products. Similarly, reactions of alpha,beta-dinitroolefins with 2-mercaptoethanol give five-membered ring products along with monosubstituted olefins and products disubstituted on one carbon. The formation of cyclic products from alpha,beta-dinitroolefins and 1,2-difunctional nucleophiles is explained ih terms of a stepwise addition-substitution mechanism in which a carbanion intermediate must be assumed. A Michael-type reaction seems to occur, and the addition intermediate loses a nitro group by intramolecular substitution. The reaction of 1,2-dinitrocyclohexene with 2-mercaptoethanol unexpectedly forms a beta'-substituted alpha-nitroolefin by means of another reaction mechanism.
