Abstract: Cycloaddition reactions of isoselenocyanates with enamines of the crotone
type as well as with diazomethane were studied. With enamines, α,ß-disubstituted selenocrotonanilides were obtained as resulting products. With
diazomethane the resulting product (IV-substituted 5-amino-l,2,3-selenodiazole) could be isolated only in the case of 4-chlorophenyl isoselenocyanate.
The structures of the synthesized compounds were proved by infrared,
ultraviolet, and nuclear magnetic resonance spectra. Preparation of the
mentioned compounds and relation between their structures and spectral
properties are discussed.
