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.
