配位导向下烯基C—H官能团化是制备多取代烯烃的常用方法, 反应通常经历弱配位基团(羟基、酰胺、羧酸、胺基等)协助下的双键在环内的金属杂环中间体(endo-metallocycle), 实现导向基邻碳位C—H官能团化, 表现出了优异的Z/E选择性, 目前发展的C—H官能团化类型丰富, 包括烯基化、烷基化、芳基化、炔基化、烯丙基化、杂原子化和多米诺环化等. 相比较而言, 导向基同碳位烯基C—H官能团化则发展缓慢, 可能是该反应需要经历更加不稳定的双键在环外的金属杂环中间体(exo-metallocycle), 严重阻碍了烯烃的配位C—H活化的发展. 近年来, 若干课题组在这方面报道了导向基同碳位烯基C—H官能团化, 包括烯基化、烯丙基化、芳基化、碘代、炔基化反应. 按C—H官能化类型介绍了配位导向下同碳位烯基C—H官能团化反应的研究进展, 并对该领域的发展前景进行了总结与展望.

Vicinal group-directed alkenyl C—H functionalization provides general method toward the synthesis of multi- substituted alkenes, proceeding by the weakly coordination-group (such as hydroxyl, amide, carboxylic acid, amino group etc.) assisted endo-cyclometallation, leading to vicinal C—H functionalization with excellent E/Z selectivities, including alkenylation, alkylation, arylation, alkynylation, allylation, domino cyclization etc. In stark contrast, geminal group-directed alkenyl C—H functionalization attracted much less attentions presumably due to the difficult formation of exo-metallocyles, which greatly inhibited the development of directed alkenyl C—H functionalization. In recent years, several groups have demonstrated the importance of geminal group-directed alkenyl C—H functionalization, including alkenylation, arylation, alkynylation, allylation and iodination. The research progress is introduced according to the types of geminal C—H functionalization, and the reaction mechanisms and applications of specific reactions are discussed. The development prospects with outlook are also summarized
