Pseudohalogen Compounds. Synthesis and Reactivity of Alkyl- and Arylammonium Dicyanamides, Tricyanmethanides, and Dicyanmethanidoacetates [RNH3]X (X = N(CN)2, C(CN)3, C(CN)2C(O)CH3)The syntheses of alkyl- and arylammonium dicyanamides, tricyanmethanido, and dicyanmethanido-acetates are reported. At higher temperatures the synthesized dicyanamides and tricyanmethanides are reacting to the corresponding cyanoguanidine and to 1,1-diamino-2,2-dicyano-ethene derivatives, respectively. The new compounds are characterized on the basis of their i.r. spectra and elemental analyses.
Notes:
Es wird über die Synthese von Alkylund Arylammoniumdicyanamiden, -tricyanmethaniden und -dicyanmethanidoacetaten berichtet. Die dargestellten Dicyanamide und Tricyanmethanide unterliegen bei höherer Temperatur einer Umlagerungsreaktion zu entsprechenden Cyanoguanidin- bzw. 1, 1-Diamino-2,2-dicyano-ethen-Derivaten. Die neuen Verbindungen werden anhand ihrer IR-Spektren und den Elementaranalysen charakterisiert.
