摘要:

以非金属硒为催化剂, 三乙胺为助催化剂, 用CO替代剧毒光气作为羰基化试剂, 通过鼓泡方式经硒催化“一锅煮”的4-氨基吡啶与硝基芳烃的氧化还原羰基化反应合成4-吡啶基脲. 通过探究反应温度、 反应时间、 溶剂及碱的种类等因素的影响, 获得了反应的优化条件. 在优化条件的基础上, 以中等到良好的收率制得4-吡啶基脲类化合物, 反应底物硝基芳烃的普遍适用性较好; 还提出了该反应的可能机理.

Abstract:

A facile, economical and environment-friendly approach to 4-pyridinylureas was reported. With cheap and easily available nonmetal selenium as the catalyst, triethylamine as the cocatalyst, carbon monoxide instead of virulent phosgene as the carbonylation reagent, the target products could be obtained via selenium-catalyzed redox carbonylation of 4-aminopyridine with nitro aromatics by bubbling of CO. The optimal reaction conditions were obtained by exploring the effects of main factors on the carbonylation reaction such as reaction temperature, reaction time, kinds of solvents and bases. Under the optimal conditions, 4-pyridinylureas could be obtained in moderate to good yields. The applicability of the substrates nitro aromatics was good. The possible reaction mechanism was also proposed at the end of this paper.
