N-(N'-Arylsulfonylbenzimidoyl)dichlorosulfimides are obtained in the reaction of N-chloro-N'-arylsulfonylbenzamidines with sulfur or sulfur dichloride.N-Chloro-N'-benzoylbenzamidine reacts with sulfur dichloride in the presence of pyridine to form N-(N'-benzoylbenzimidoyl)dichlorosulfimide.Thermolysis of the latter gives 1,3,5-triphenyl-sym-triazine.When N-chloro- or N,N-dichloro-N'-benzoylbenzamidines are heated with an excess of sulfur dichloride, 2,4-diphenyl-1,3,5-thiadiazole is formed.The reaction of N-chloro-N'-benzoylbenzamidine with thionyl chloride gives N-(N'- benzoylbenzimidoyl)sulfinylamine, which decomposes with the formation of 1,3,5-triphenyl-sym-triazine when heated in inert solvents.

Several 4,5-diamino-4,5-dihydroimidazoles, 1, have been synthesized in order to study the effects of the substituents in the imidazole ring on the rearrangement to N-(1,2-diaminoethylidene)amidine, 2.The rate of the process increases with the increase in
