Abstract
The direct α-Csp3–H functionalization of simple ethers is a vital strategy among radical reactions.
This review discusses their applications according to the starting materials: (1)
reactions with alkenes or alkynes; (2) reactions with other unsaturated compounds;
and (3) reactions with nucleophilic partners. Mechanisms like radical addition, C–H
activation, elimination, metal-catalyzed coupling, cyclization, oxidation, and rearrangement
will be analyzed herein.
