Co–Catalyzed Oxidative Alkylation between Styrenes and Cyclic Ethers via sp3 C−H Functionalization

Abstract A new cobalt‐catalyzed oxidative alkylation from readily available styrenes and ethers has been disclosed for a rapid and highly efficient construction of C−C bond via sp3 C−H bond functionalization. Various substituted styrenes and cyclic ethers are well investigated and give satisfactory results. Preliminary mechanism studies suggested that this transformation may involve a radical process. This methodology was demonstrated by good yields and functional group compatibility with simple operation, easily available starting materials and low catalyst loadings.
