The reaction of benzynes with thiophene-1,1-dioxides afford the Diels-Alder cycloadducts which spontaneously lose sulphur dioxide to give the corresponding naphthalene derivatives in moderate yields.Further reaction of benzyne with naphthalenes yielding dibenzobarrelenes is observed in a few cases.
