  comparative rates of cyclotrimerization of dimethylacetylenedicarboxylate (DMAD) and hex-3-yne have been studied with the catalysts [η5-C5R5)Rh(COD)] (R = H, Me, Cl; COD = cycloocta-1,5-diene), [(η5-C5R5)Rh(CO)2] (R = H, Me), [(η5-C5Me5RhL2] (L = C2H4, PF3) and [(η5-C5H4PPh3)Rh(CO)2]+ PF6− under pseudo-first-order conditions. In these reactions, which all obey the rate law, rate = kobs [acetylene], the rate

• Iridium Complex-Catalyzed Highly Selective Cross [2 + 2 + 2] Cycloaddition of Two Different Monoynes:  2:1 Coupling versus 1:2 Coupling
  作者：Ryo Takeuchi、Yoshihiko Nakaya

  DOI：10.1021/ol035330d

  日期：2003.10.1

  Highly selective cross [2 + 2 + 2] cycloaddition of two different monoynes is achieved by using a catalytic amount of [Ir(cod)Cl](2) and ligand. The ligand had a considerable effect on the reaction. When 1,2-bis(diphenylphosphino)ethane was used, two molecules of dimethyl acetylenedicarboxylate (DMAD) reacted with one molecule of a monoyne to give the 2:1 coupling product. When 1,2-bis(dipentafluorophenylphosphino)ethane was used instead of dppe, one molecule of DMAD reacted with two molecules of a monoyne to give the 1:2 coupling product.
