Nitriles in Heterocyclic Synthesis. Novel Synthesis of Pyridazine Derivatives
The crotononitriles 1a-c coupled with arene-diazonium salts to yield either the acyclic mono- or dihydrazones depending on coupling reaction conditions.Both mono- and dihydrazones could be cyclized to the corresponding pyridazine derivatives.Direct format
NITRILES IN HETEROCYCLIC SYNTHESIS: NOVEL SYNTHESIS OF PYRIDAZINE DERIVATIVES
The crotononitrils 1a-c coupled with aryldiazonium salts to yield either the acyclic hydrazones or azahydrazones depending on coupling reaction conditions.Both hydrazones and azodrazones could be cyclized to the corresponding pyridazine derivatives.Direct
