New heterocyclic precursors for thermal generation of reactive, electron-rich 1,2-diaza-1,3-butadienes

Figure presented The preparation and thermolysis of new stable heterocyclic precursors of 1,2-diaza-1,3-butadienes is described. The resulting reactive diazadienes are trapped in situ with N-phenyldiazamaleimide. The effect of precursor structure on the temperature at which the diazadienes are generated is discussed.

Cycloaddition Reactions of Sulphines and Thiones with Azoalkenes

Fluorenethione S-oxide undergoes (2+4) cycloadditions with azoalkenes to yield 2H-1,2,3-thiadiazine 1-oxides together with a small amount of the regioisomeric 6H-1,3,4-thiadiazine 1-oxides.Fluorenethione, with azoalkenes, undergoes (2+4) regiospecific cycloaddition reactions leading to the formation of 6H-1,3,4-thiadiazine derivatives.Diarylsulphines and diarylthiones fail to react with azoalkenes.
