ligands is of ongoing interest. In this report, the one-step syntheses of a series of (pyridylalkyl)amine derivatives is described. The reported compounds contain both pyridine rings and sp 3 -hybridized nitrogen as potential donor sites. The general synthetic method involves- a room temperature reaction of mono-, bis-, tris-, or tetrakis-(bromomethyl)benzenes with an excess of (pyridylmethyl)amine in
新的多齿含氮配体的合成一直受到关注。在本报告中,描述了一系列(吡啶基烷基)胺衍生物的一步合成。报道的化合物含有吡啶环和sp 3 杂化氮作为潜在的供体位点。一般的合成方法包括单-、双-、三-或四-(溴甲基)苯与过量的(吡啶基甲基)胺在四氢呋喃中的室温反应。产物可以通过蒸馏、色谱法或重结晶进行纯化,并以相当高的收率获得。这种合成方法的优点是程序简单且起始材料易于获得。
