尽管离子基在19世纪就已经发现,但由于其活性高、寿命短,直至近30年来,随着有机理论和实验技术的进步,人们对离子基才有了较深入的了解.已有证据表明,许多过去曾被认为按极性历程进行的经典的有机反应实际上可能是经历了离子基的生成而按单电子转移(SET)历程进行的.离子基亦被证明是在许多重要的生化反应和生命过程中广泛存在的一种重要的活泼中间体,离子基化学已成为当今有机化学研究的新热点之一. Although ionic groups have been found in the 19th century, they have gained a deeper understanding of ionic groups as organic theory and experimental techniques have progressed until nearly 30 years due to their high activity and short lifetime. , Many classical organic reactions that were previously thought to proceed by polar history may in fact have undergone a single electron transfer (SET) course through ionic group generation Ion groups have also been shown to be involved in many important biochemical reactions And living in the process of an important lively intermediate, ion-based chemistry has become a new hot topic in organic chemistry today.
