2‐Aza‐1,3‐dienes. Synthesis and Properties of 1‐Alkylpyrazone‐imines and their Tautomers Treatment of 5‐dialkylamino‐1,1‐dicyano‐2‐aza‐1,3‐dienes (or their 1‐methoxycarbonyl analogoues) with primary amines gives substituted 1‐alkyl‐3‐cyano‐(or methoxycarbonyl‐)pyrazoneimines. Tautomeric behaviour, nucleophilic addition to imino function and spectroscopic data of these isomers are examined.
