  Synthese und Reaktionen von 2-Arylhydrazono-2-cyan-N,N-dialkyl-acetamidinen

  摘要：

  The title compounds 3 were synthesized by reaction of arlyhydrazono-malononitriles 1 with secondary amines and used for subsequent cyclization reactions. Thus, 3 undergoes cyclooxidation by treatment with CuSO4/pyridine to form the 5-dialkylamino-2-aryl-1,2,3-triazolo-4-carbonitriles 4. From 4 a and hydrazine hydrate/DMF the 4-(1,3,4-triazolyl-5)-1,2,3-triazole 5 c is obtainable. The chloroacetylation of 3 is accompanied by hydrolysis of the amino group to yield the arylhydrazono-N-chloracetyl cyanoacetamides 6. The quaternisation of 6 with pyridins is followed by the Thorpe cyclization to form the 4-amino-5-arylazo-6-hydroxy-3-pyridinio-pyrid-2-on-chlorides 8, useful as cationic dyes. The reaction of 3 with trichloroacetonitriles yields the 5-arylazo-4-imino-2-trichlormethyl-1,4-dihydropyrimidines 10 a-c which can be converted into the 5-arylazo-2-hydrazino-pyrimidine derivatives 10 d-f.From 10 d the 6-phenylazo-triazolo[4,3-a]pyrimidine derivative 11 is obtainable. From 3 and phenylisothiocyanate the 5-arylazo-4-imino-1,4-dihydropyrimidin-2-thiones 12 arise. The structures were investigated by C-13-NMR-spectroscopy.
