The reaction of 3-oxo-3-phenyl-2-phenylhydrazonal with functionally substituted and heteroaromatic substituted acetonitrile to yield arylazonicotinic acid derivatives and 5-arylsubstituted pyridines was established. In some cases the produced nicotinates could not be isolated as they underwent thermally induced 6π-electrocyclization yielding polynuclear pyridine derivatives.
建立了 3-氧代-3-苯基-2-苯腙与功能取代和杂芳环取代的乙腈反应生成芳基偶氮烟酸衍生物和 5-芳基取代吡啶的方法。在某些情况下，由于所生成的烟酸酯不能分离，因为它们经历了热诱导的 6π-电环化反应，生成多核吡啶衍生物。
