The main differences between our study and Fang's study are that in Fang's study, the effects of the trifluoromethane sulfonate anion (OTf, and the different ligands of PPh3, PMe3, and PH3 on the overall catalyzed reactions have not been taken into account and the role of two nucleophilic molecules MeOH in the proton migration is not investigated. As demonstrated in our study, the anion OTf- plays a key role in the [AuL]OTf (L, PPh3, PMe 3, PH3, OTf, trifluoromethane sulfonate) catalyzed reaction. In dynamics, the intimate ion pair [AuL]OTf-catalyzed reaction pathways are more favored than the cation [AuL, catalyzed channels. The effect of the different ligands on the reaction is remarkable. The proton migration by two nucleophilic molecules MeOH appears easier
