Abstract An efficient and convenient copper-catalyzedthree-componentreaction has been developed for the arylselenation of phenols with Se powder and aryl iodides. This one-pot procedure provides a straightforward approach to the synthesis of ortho-arylselenylphenols with high regioselectivity. This practical process shows good functional group tolerance, providing the corresponding products in moderate
Direct sulfenylation and selenylation of phenols using a stoichiometric amount of FeCl3 under an oxygen atmosphere has been developed. The chalcogenated phenols were shown to be suitable for preparing S- and Se-containing compounds using the reaction of the remaining hydroxy group.
