  醇通过CeO2上的C-N键裂解使叔胺醇化

  摘要：

  已经发现CeO 2促进叔酰胺形成酯的醇解反应。本催化体系操作简单，可回收，并且不需要添加剂。酯化过程显示出较宽的底物范围（> 45个实例；分离产率高达93％）。密度泛函理论（DFT）研究与现场FT-IR观察相结合的结果表明，该过程通过速率限制将CeO 2晶格氧加到吸附的乙酰胺类化合物的羰基上进行，能量垒为17.0 kcal / mol 。该值与通过分析Arrhenius图获得的实验值（17.9 kcal / mol）很好地匹配。原位进一步研究FT-IR和使用探针分子的程序升温脱附表明，酸性和碱性性质均很重要，因此，CeO 2对CN键断裂反应表现出最佳性能。
