for carbamate-directed -C-H bond arylation of biphenyl derivatives employing diaryliodonium salts as the arylation agents was explored. Consequently, the Scholl reaction was utilized to cyclize the product, yielding 21 varieties of multifunctional triphenylene derivatives. The maximum yield achieved through this two-step process was 94 %, offering an efficient synthesis route for the production of multi-substituted
探索了一种使用二芳基碘鎓盐作为芳基化剂的氨基甲酸酯导向的联苯衍生物-C-H键芳基化的新方法。因此,利用Scholl反应将产物环化,得到21种多官能苯并菲衍生物。通过该两步工艺实现的最大产率为 94%,为生产多取代苯并菲衍生物提供了一条有效的合成路线。
