Olefins are one of the versatile functional groups and intermediates in organic synthesis.1As one of the most essential transformations,C=C double bond is still widely used in current organic synthesis.In recent years,N-tosylhydrazones are also considered as a vital carbene precursors in palladium-catalyzed coupling reaction.2 Over the past decade,the groups of Barluenga and Wang have made significant progress towards palladium-catalyzed coupling reactions by using N-tosylhydrazones as the coupling partner.3 In addition,spirocyclohexadienones are a kind of significant structural frames in many natural products and pharmaceuticals.4 Based on the importance of C=C double bond formation,we report herein a novel Pd-catalyzed reaction of N-tosylhydrazones with dearomative vinyl iodide approach affords olefin derivatives,which proceeds via a migratory insertion of Pd carbene.A series of olefin derivatives are obtained in excellent yields.
