Abstract

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.
