Abstract

A visible-light-induced oxidative difunctionalization of activated alkenes with simple ethers via selective C(sp3)–H bond cleavage and dual C–C bond formation was developed. The reaction provides mild, efficient and atom economical access to alkylated oxindoles at room temperature under metal-free conditions.
