摘要：

The type of ligand oil in an allenylpalladium complex, which was prepared from propargyl alcohol derivative and Pd(0), plays an important role in determination of the ring size of the cyclized compound. An intermediary palladium complex bearing a monodentate ligand gave a cyclized compound via palladacycle, while that bearing a bidentate ligand gave one-carbon elongated cyclized compound via a eta(3)-propargylalladium complex.
