Efficient imidation of C(sp³)–H bonds adjacent to oxygen atoms of aryl ethers under metal-free conditions

Abstract

An intermolecular oxidative C-N formation reaction of aryl ethers with pharmacological saccharins was realized under metal-free conditions for the first time. The understanding of the intrinsic characteristics between C(sp(3))-H and C(sp(2))-O bonds of aryl ethers and their potential for application might promote more research interest in this area.
