The syntheses of BEDT-TTF (ET) derivatives with potential metal ion binding pyridyl, bipyridyl and terpyridyl groups is achieved either by stepwise construction of the organosulfur core or via reactions of hydroxymethyl-ET for which a cheap and efficient four step route is reported. The tosylate of hydroxymethyl-ET, reported for the first time, undergoes nucleophilic substitutions with pyridyl, bipyridyl-
的合成 BEDT-TTF (ET)具有潜在金属离子键的衍生物 吡啶基, 联吡啶可以通过逐步构建有机硫核或通过羟甲基-ET的反应获得叔丁基和叔吡啶基,据报道该反应是廉价而有效的四步途径。首次报道的羟甲基-ET的甲苯磺酸盐经历了亲核取代吡啶基,联吡啶基和联吡啶基硫醇盐提供新的供体。两种取代的ET衍生物的X射线晶体结构通过围绕ET基团的短分子轴弯曲而显示出有机硫供体体系与平面度的显着偏差。
