Easy Copper-, Ligand- and Amine-Free Sonogashira Coupling Reaction Catalyzed by Palladium on Carbon at Low Catalyst Loading and by Exposure to Air

The author list and contact information for this manuscript were incomplete. The results reported in this Letter were all carried out in the Laboratory of Medicinal Chemistry, Gifu Pharmaceutical University, Japan under the supervision of Professors Hironao Sajiki and Kosaku Hirota. The single author, Guolin Zhang, was a visiting research associate during one year at that laboratory. The results were illegally published by Guolin Zhang without authorization by Professors Hironao Sajiki and Kosaku Hirota and Gifu Pharmaceutical University. The author apologizes for misrepresenting the research covered in this paper as his work alone.

Therefore, the correct information is as follows:
