摘 要: | 介绍了近年来国内外在温和条件下碳氢单键直接官能团化反应的最新进展。官能团化反应的特点是,在常温常压和紫外光促进下,用过渡金属配合物催化碳氢单链活化,使烷烃、芳烃等烃类的碳氢单键直接官能团化,从而达到直接利用各种烷烃及芳烃作为化工原料合成有机化工产品的目的。通过紫外光催化可以使反应在常温常压下进行,能克服传统工艺能耗高、选择性差的缺陷。经不断深入研究,该反应可望在21世纪成为环境友好的有机合成工艺。

A new method of direct functionalization of C H bonds under ambient conditions |
| |
Abstract: | The recent development both at home and abroad is introduced on direct functionalization of C H bonds under mild conditions. Activation of C H bonds can be done under ambient temperature and pressure promoted by UV light using transition metal complexes as catalyst. In this way, C H bonds of paraffin and aromatics are functionalized directly and organic products directly synthesized from paraffin and aromatics as raw material. With low energy requirement and high selectivity, those reactions are expected to be environment friendly organic synthesis technologies in next century. |
