摘要:
N,N'-Bis[(1-methyl-3-oxobutylidene)hydrazinocarbonylethyl]-, N,N'-bis[(2,5-dimethylpyrrol-1-yl)carbamoylethyl]-, N, N'-bis(phenylureidocarbamoylethyl)-, N, N'-bis(phenylcarbamoyl)-, N, N'-bis(phenylureidocarbamoylethyl)-, and N, N'-bis[(4,5-dihydro-5-oxo-4-phenyl-1,2,4-triazol-3-yl)ethyl]-1,4-phenylenediamines, 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.
