Synthesis of 3-Sulfanylsubstituted 5-Amino-1-phenyl-1<i>H</i>-pyrazol-4-carbonitriles
By the interaction of 2-(bis(alkylthio)methylene)malononitriles with phenylhydrazine previously unknown representatives of 5-amino-1-phenyl-1 H -pyrazole-4-carbonitriles were obtained. It was found that using 2-(1,3dithiolan-2-ylidene)malononitrile in this reaction 3,3'-{[disulfanidylbis(ethane-2,1-diyl)]bis(sulfanidyl)}bis(5amino-1-phenyl-1 H -pyrazole-4-carbonitrile) is formed.
