Reaction of vinylidenecyclopropanes with diphenyl diselenide in the presence of AIBN and further transformation to produce new naphthalene derivatives

The reactions of vinylidencyclopropanes with diphenyl diselenide in the presence of AIBN produced the corresponding products in moderate to good yields under mild conditions. The transformation of the corresponding products to methylenecyclopropanes (MCPs) can be further converted to the corresponding naphthalene derivatives by treatment with 30 mol % of TfOh in dichloromethane.
