Structural Features of Certain p-substituted Phenyl 2-nitrovinyl Sulfones
The structure of p-substituted phenyl 2-nitrovinyl sulfones was studied through different spectral methods. It has been found that the nucleophilic substitution reactions of sodium phenylsulfinates with 1-chloro-2-nitroethene occur stereospecifically. The

Highly stereoselective preparation of nitro olefins and nitro dienes by the addition-elimination of copper-zinc organometallics to β-alkylthio and β-phenylsulfonyl nitro olefins
The addition-elimination of copper-zinc organometallics RCu(CN)ZnX to (E)-1-nitro-2-phenylsulfonyl ethylene 2a gave highly functionalized pure (E) nitro olefins and stereoselectively (1E, 3E) and (1E, 3Z)-1-nitrodienes in excellent yields. β-Alkylthio nit

β-SULFONYLNITROOLEFINS AS VERY REACTIVE ALKYNE-EQUIVALENTS IN DIELS-ALDER REACTIONS
Very reactive dienophiles, β-sulfonylnitroolefins, are prepared starting from β-nitro alcohols.The high activation due to the nitro and the sulfonyl groups promotes the Diels-Alder reaction to various dienes under mild conditions.Reductive elimination of
