Abstract

N-(Iminyl)pyridinium salts are a rare and poorly explored class of pyridine derivatives. In this work, we propose a method for the synthesis of these compounds from methyl nicotinate and hydrazones of aromatic ketones. The method involves N-arylation of pyridine with 2,4-dinitrophenol tosylate and subsequent reaction of the arylpyridinium salt with the amino group of N-unsubstituted hydrazones (the Zincke reaction).

利用锌克反应从酰肼合成 N-(亚氨基)吡啶鎓盐

N-(Iminyl)吡啶鎓盐是一类罕见的吡啶衍生物，对它们的研究很少。在这项工作中，我们提出了一种从烟酸甲酯和芳香酮的酰肼合成这些化合物的方法。该方法包括吡啶与 2,4-二硝基苯酚对甲苯磺酸盐发生 N-芳基化反应，然后芳基吡啶鎓盐与 N-未取代肼的氨基发生反应（Zincke 反应）。
