Addition of diazoacetonitrile to para-substituted N-benzilidene-anilines has been studied. The addition is easier if the substituent is an electrodonating group. Products obtained are Δ2-1,2,3-triazolines or aziridnes, and enamines resulting from the decomposition of the triazolines with migration of the 5-aryl substituent. Decomposition of the triazolines under various conditions has also been studied

Several new 3-aminopyrrole derivatives have been synthesized from 3-substituted amino-2-phenylacrylonitriles using Thorpe-Ziegler cyclization. These substituted pyrroles are readily converted into 5H-pyrrolo[3,2-d]pyrimidines (9-deazapurines).
