摘要/Abstract

自由基正离子盐早在一百多年前就被制备出来，近年来，随着自由基化学的复兴，自由基正离子盐促进的有机化学转化受到了广泛地关注.在早期的研究中，自由基正离子盐主要被用于单电子氧化反应，可以高效地实现环加成、碎裂、重排等反应.与此同时，近期的研究表明，自由基正离子盐还可以促进C—H键的需氧氧化，实现一系列C—H键的直接官能团化反应.本综述按照自由基正离子盐促进的反应类型，总结了这一领域的最新进展.

The first radical cation salt (RCS) was prepared more than 100 years ago, and with the recent renaissance of radical chemistry, the RCS promoted organic transformations attrack extensively attention. In early research, RCS was mainly used to initiate single electron oxidation reactions, such as cycloaddition, fragmentation, rearrangement and so on. Recently, RCS was used to induce the aerobic oxidation of C—H bond, and achieved a series of direct functionalization of C—H bond. In this review, prominent examples from the recent literatures are organized on the basis of the different reactions enabled by RCS catalysis.
Key words: radical cation salt, single electron oxidation, C—H activation, cycloaddition
