摘要
A fast, scalable, and safer C-sp(3)-H oxidation of activated and un-activated aliphatic chains can be enabled by methyl(trifluoromethyl)dioxirane (TFDO). The continuous flow platform allows the in situ generation of TFDO gas and its rapid reactivity toward tertiary and benzylic Csp(3)-H bonds. The process exhibits a broad scope and good functional group compatibility (28 examples, 8-99 %). The scalability of this methodology is demonstrated on 2.5 g scale oxidation of adamantane.
