Merging cobalt and photoredox catalysis for the C8–H alkoxylation of 1-naphthylamine derivatives with alcohols

Abstract

A combined cobalt and photoredox catalysis system to realize the C8–H alkoxylation of 1-naphthylamine derivatives with alcohols was developed. Using commercially available alkyl alcohols as raw materials and Co(OAc)₂ and rose bengal as catalysts, 1-naphthylamine derivatives reacted with alcohols to generate the corresponding C8–H alkoxylation products in good yields.
