Co-Catalyzed Hydroarylation of Unactivated Olefins

Abstract

A mild, general, scalable, and functional group tolerant intramolecular hydroarylation of unactivated olefins using a Co(salen) complex, a N-fluoropyridinium salt, and a disiloxane reagent was reported. This method, which was carried out at room temperature, afforded six-membered benzocyclic compounds from mono-, 1,1- or trans-1,2-di, and trisubstituted olefins.
