Abstract
En 中文
The cycloheptatrienyl (tropylium) ion is a planar, fully conjugated seven-membered carbocycle containing six pi-electrons. It features a delocalized positive charge, making it a one-carbon homolog of benzene. Owing to its unique electronic structure and facile accessibility, the tropylium ion has recently attracted increasing attention as a versatile reagent in organic synthesis. It has been employed as a Lewis acid and an oxidant in various organic transformations. Furthermore, tropylium-based compounds have emerged as functional materials, including organic dyes and stimuli-responsive systems. This review summarizes recent developments in tropylium-mediated organic synthesis and highlights the intriguing properties and potential applications of tropylium ion derivatives.
