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.

CH3OH分子参与质子转移过程，使得原本通过四元环结构过渡态的质子转移过程通过六元环结构过渡态实现，从而极大地降低了质子转移过程的活化能，碳-碳键形成过程进而成为反应的速度控制步骤，研究结果与Aggarwal等的最新动力学研究成果相吻合。
