Aviles, T., S. Jansat, M. Martinez, F. Montilla, and C. Rodriguez. "Deactivation of the Cobalt Catalyst for the Cyclotrimerization of Acetylenes in Ionic Liquids: Solvent Effects on the Mechanism and Thermal and Pressure Activation Parameters." Organometallics. 30 (2011): 3919-3922. AbstractWebsite

The deactivation reaction of the [CoCp(1,4-sigma-C(4)-[Ph](4))PPh(3)] catalyst for the cyclotrimerization of acetylenes has been kinetico-mechanistically studied under different temperature, pressure, and solvent conditions. The results indicate a dramatic change in mechanism from conventional to ionic liquid solvents due to the polarity of the medium.
