Palladium-catalyzed insertion of α,β-unsaturated N-tosylhydrazones and trapping with carbon nucleophiles.
Palladium-catalyzed carbene migratory insertion-cyclization reactions were reported, delivering dihydronaphthalene and indene derivatives in moderate to good yields. A three-component cross-coupling was also developed. The reactions are easy to handle, under mild conditions and various functional groups are tolerated.
