title: Mechanistic evidence for remote pi-aryl participation in acid-catalyzed ring opening of homobenzoquinone epoxides.
abstract: The acid-induced reaction of bis(p-chlorophenyl)homobenzoquinone epoxide gave the dual ipso/ortho intramolecular S(E)2-Ar products associated with pi-aryl participated oxirane ring opening, whereas bis(p-tolyl)- and diphenyl-substituted homologues provided only the ortho products.
