Copper-catalysed oxidative C–H/C–H coupling between olefins and simple ethers

Abstract

The first copper-catalysed oxidative alkenylation of simple ethers to construct allylic ethers was successfully achieved. Different substituted olefins and simple ethers could be cross-coupled well to generate the corresponding alkenylation products. Notably, open-chain ethers were also found to be efficient coupling partners in this reaction. This reaction is likely to proceed via a radical process.
