摘要：

The dipolar cycloadducts from diaryl azines and maleimides ((1) under bar, <(20)under bar>) or maleic anhydride (<(18)under bar>) have been reacted with chlorosulfonic acid to give the bis- ((2) under bar, <(19)under bar>) or tetrachlorosulfonyl derivatives (<(21)under bar>). The chorosulfonation generally required addition of thionyl chloride. The various sulfonyl chlorides were converted into a range of sulfonamides ((3) under bar-<(11)under bar>, <(13)under bar>-<(16)under bar>) and the N-butylsulfamate (<(12)under bar>). The N,N-dialkylsulfamonyl cycloadducts (<(23)under bar>, <(25)under bar>) were also obtained by cycloaddition of the bis-dimethylsulfamoyl 2-methoxybenzaldehyde azine (<(22)under bar>) and N-phenyl maleimide or the N-((p) under bar-diethylsulfamoylphenyl) maleimide (<(24)under bar>) with (p) under bar-tolualdehyde azine, although the former reaction did not go to completion. Attempts to carry out the cycloaddition between the two sulfamoyl reactants (<(22)under bar> and <(24)under bar>) were unsuccessful. The various sulfonamide derivatives will be screened as pesticides.
