efficient C‐Hactivation, which has attracted increased interest in organic chemistry. In this account, we describe a CuI‐catalyzed oxidative coupling between nitrones and various ethers or amines as an example. Predictable site‐selective C‐C bond formation was achieved throughactivation of the C‐H bonds in each coupling partner and the migration of a C‐N double bond. Mechanisticstudies strongly suggested
