N,N'-Bis[(1-methyl-3-oxobutylidene)hydrazinocarbonylethyl]-, N,N'-bis[(2,5-dimethylpyrrol-1-yl)carba-
moylethyl]-, N,N'-bis(phenylureidocarbamoylethyl)-, N,N'-bis(phenylcarbamoyl)-, N,N'-bis(phenylureido-
carbamoylethyl)-, and N,N'-bis[(4,5-dihydro-5-oxo-4-phenyl-1,2,4-triazol-3-yl)ethyl]-1,4-phenylene-diamines, and their thio analogs were obtained by the condensation of N,N'-bis-(hydrazinocarbonylethyl)-1,4-phenylenediamine with 2,4-pentanedione, 2,5-hexanedione, phenyl isocyanates, or phenyl isothiocyanates (with subsequent treatment of the obtained semicarbazides with alkali), and carbon disulfide respectively.
