Abstract An improved method for the synthesis of carboxamide ligands containing thioether donor sites is described. This replaces the pyridine as the reaction medium used in the classical method by tetrabutylammonium bromide. The desired products, 1,4-bis[o-(R-2-carboxamidophenyl)]-1,4-dithiobutane, R = quinoline (1), furan (2), thiophene (3), pyridine (4), and pyrazine (5), were obtained in good yields
摘要 描述了一种用于合成含有硫醚供体位点的甲酰胺配体的改进方法。这用四丁基溴化铵代替了吡啶作为经典方法中使用的反应介质。所需产物,1,4-双[o-(R-2-甲酰氨基苯基)]-1,4-二硫代丁烷,R = 喹啉 (1)、呋喃 (2)、噻吩 (3)、吡啶 (4) 和吡嗪 (5) 以良好的收率和更短的反应时间获得。图形概要
