Abstract

Abstract : A formal dual C(sp 2 )–H cross-dehydrogenative C–O bond formation reaction between phenols and naphthylamine derivatives to construct diaryl ethers has been developed under mild conditions. Abstract : A formal dual C(sp 2 )–H cross-dehydrogenative C–O bond formation between phenols and N -substituted naphthylamines to expediently assemble diversely functionalized diaryl ethers bearing hydroxyl and amino functionalities with excellent atom and step economy was developed under mild conditions. The reaction features three C–H cleavages and three C–O bond formations in one pot. In addition a rare C(sp 2 )–O bond formation rather than the conventional C–C bond formation took place by addition to a carbonyl O atom of the in situ generated ortho -quinone.
