近几十年来,钯催化C—H键的选择性官能团化反应已成为有机合成中构建C—C键的重要策略,基本可以分为三类反应模式:C—H键与芳基或烷基卤化物(或拟卤化物)的交叉偶联反应、C—H键之间的交叉脱氢偶联反应、C—H键与金属有机化合物的交叉偶联反应。本文综述了该领域的最新研究进展,介绍了各类反应的特点、优势及在合成中的应用,提出了今后研究和发展的重点及方向。
In past decades, palladium-catalyzed direct selective C-H bonds functionalization has become a highly attractive strategy in organic synthesis and represents a highly desirable goal. This review introduces three extensively investigated modes for forming C-C bonds from C-H bonds via palladium catalysis: cross-coupling reactions of C-H bonds with aryl or alkyl halides/pseudohalides, cross-dehydrogenative couplings of two C-H bonds, and cross-coupling reactions of C-H bonds with organometallic reagents. A comprehensive summary of recent advances and detailed analysis on the versatility and practicality of these transformations are presented. The research trend for this strategy is also prospected.
