B3LYP/6-311++G** calculations have been carried out to study the trimethylamine-catalyzed Baylis-Hillman reaction between acraldehyde and formaldehyde in the solvent of methanol using a supermolecular model. The optimized geometries and energies of all the species involved in the reaction were obtained, and the relative energy profile was completed. The microscopic process of the Baylis-Hillman reaction in the solvent of methanol was discussed.
