Superacid-promoted synthesis of polychlorinated dibenzofurans [PDF]

Tetrahedron Letters, 2016
Abstract Polychlorinated dibenzofurans have been prepared in one step by the condensations of o -chloranil with arenes in triflic acid. A mechanism is proposed involving formation of a monoprotonated quinone (carboxonium ion), electrophilic attack at the arene, and cyclization of a carbocation intermediate.
