Provided are novel organic electroluminescent compounds and an organic electroluminescent device using the same. Since the organic electroluminescent compound exhibits high luminous efficiency in blue color and excellent life property, it may be used to manufacture OLEDs having very superior operation life.
2-aryl-3-arylazoacrylonitriles are synthesized while attempting the intramolecular N-arylation of 5-aminopyrazoles, using the hypervalent iodine reagent. The synthesis involves phenyl iodine diacetate-assisted ringopening of 5-aminopyrazoles at room temperature. A plausible mechanism for the formation of azoalkenes is proposed.
