A two-step strategy for the transition-metal-free C-H functionalization of arenes using unsym. iodonium salts as versatile synthetic linchpins was presented. The key to the success of this strategy was the identification of the 3,5-dimethyl-4-isoxazolyl (DMIX) group as a superior dummy ligand, which enabled not only site-selective C-H functionalization to afford unsym. iodonium salts I [R = Ph, 2-thienyl, 3,4-di-ClC6H4, etc.; X = OAc, OTs], but also highly selective aryl transfer during the subsequent metal-free coupling reaction. Both electron-rich and moderately electron-deficient arenes could be converted into the iodonium salts through C-H functionalization, allowing for diverse structural elaboration by metal-free C-N, C-C, C-S, and C-O coupling.Diethyl 2-methylmalonate(cas: 609-08-5SDS of cas: 609-08-5) was used in this study.
Diethyl 2-methylmalonate(cas: 609-08-5) belongs to aliphatic hydrocarbons. Aliphatic hydrocarbons belong to the most abundant fraction in crude oil. Aliphatics molecules are linear or branched open-chain structures such as n-alkanes, isoalkanes, cycloalkanes (naphthenes), terpenes and steranes.SDS of cas: 609-08-5
