Hydroxy-Group-Facilitated Vinylic Iodination of ortho-Vinylnaphthols Using Molecular Iodine

Abstract

An efficient and simple one-pot method for the iodination of ortho-vinylnaphthols using molecular iodine is disclosed. The reaction is believed to proceed through formation of quinone methide intermediate. The method tolerates different functional groups and provides corresponding ortho-iodovinylnaphthols in good to excellent yields.
