Iodine-promoted 2-arylsulfanylphenol formation using cyclohexanones as phenol source†
Abstract
A novel method for the formation of 2-arylsulfanylphenols using cyclohexanones as phenol source via dehydrogenation is described. Various aromatic sodium sulfinates and sulfonyl chlorides acted as efficient coupling partners to construct new C–S bonds in the presence of an iodine promoter.
