Methanol molecule participates in the proton transfer process, which takes place by a intermolecular six-membered proton-transfer transition state structure instead of the intramolecular four- membered. Consequently, the activation energy of the proton-transfer process is reduced greatly,resulting in the carbon-carbon bond formation process become the rate-determining step. The results are consistent with Aggarwal's the latest dynamics experiments.
