General description

吡啶是一种碱性N-杂环化合物。它可充当氮供体配体并形成许多金属-吡啶复合物。其具有四面体和八面体几何形状的复合物可通过红外光谱研究来进行区分。

Application

吡啶（py）可用于制备氧化钒纳米颗粒以及苯二甲酸铁，Fe(OH)(BDC)(py)_0.85（BDC = 1,4-苯二甲酸酯，py =吡啶）。它可被用作Knoevenagel缩合反应中的催化剂。

吡啶可作为一种基质用于以下的转化：

烷基三氯硅烷至三甲氧基烷基硅烷，而其可用作制备烷基硅酸盐的前体。
1-茚满酮至1-茚满酮肟，而其可进行还原性环扩展以形成四氢喹啉。

它也可用于在不使用过渡金属催化剂的情况下催化卤代芳烃的硼酸化反应以形成芳基硼酸盐。
