Popis: Reactions of l-(benzotriazol-l-yl)-l-(4-R-phenylamino)- and l-(3,5-dimethylpyrazol-l-yl)-l-(4-R-phenylamino)-2-nitro-3,4,4-trichloro-l, 3-butadienes and also l-(benzotriazol-l-yl)-l-(4-R-phenylamino)- and l-(3,5-dimethylpyrazol-l-yl)-l-(4-R-phenylamino)-2-nitro-4-bromo-3,4-dichloro-l,3-butadienes (R = EtO, MeO, Me) with amines proceed with replacement of the terminal chlorine in the trichlorovinyl group or of bromine in the bromodichlorovinyl group by an amine rest to yield the corresponding l-azolyl-4-amino-l-arylamino-2-nitro-3,4-dichloro-l,3-butadienes. When binucleophilic reagents (ethylenediamine and 2-aminoethanol) are used only one N-nucleophilic site of the nucleophile takes part in the reaction.
