单电子转移和离子基反应是物理有机化学中的一个小分支,而这个分支的特别活跃的前沿或交盖区域即是单电子转移反应。自1965年Kornblum和Russel发现S_(RN)1型反应以来,涉及单电子转移反应的各方面的工作都得到了迅速的发展。这不仅使物理有机化学的内容更加丰富,而且对许多新兴的学科领域,如金属有机化学、有机光化学、有机导体、光合作用、酶反应机理等都有很重要的意义。过二硫酸盐是一种有效的单电子转移试剂,在反应中不仅能方便地生成离子自由基,而且在不同金属离子的存在下可使有机物发生选择性氧化。这对
Single electron transfer and ion-based reactions are a small branch of physical organic chemistry, and the particularly active frontier or capping region of this branch is the one-electron transfer reaction. Since Kornblum and Russel discovered S 1 (RN) 1 type reactions in 1965, there has been a rapid development in all aspects of single-electron transfer reactions. This not only makes the content of physical organic chemistry more rich, but also has important significance to many emerging disciplines, such as metal organic chemistry, organic photochemistry, organic conductor, photosynthesis, enzyme reaction mechanism and so on. Peroxodisulfate is a potent single electron transfer reagent, which not only can generate ionic free radicals easily, but also can selectively oxidize organic compounds in the presence of different metal ions.
