Quantum chemical study of SO<sub>3</sub> introduction into sulfonic acids esters. Part III. Autocatalytic effect of sulfur trioxide
The monomolecular and bimolecular reaction of the sulfur trioxide introduction into methanesulfonic acid methyl ester as an example has been studied by the HF/6-31+G(d,p) ab initio method. The autocatalytic effect of the sulfur trioxide has been shown.
