Theoretical model of the n-propylbenzene formation in the benzene isopropylation over zeolites. An anti-Markovnikov-type proton addition promoted by the steric effect of MFI and MEL zeolite channels

Article Abstract:

Ab initio quantum mechanical calculations were used to investigate proton-catalyzed bimolecular reaction of isopropylbenzene with benzene leading to n-propylbenzene. According to computations on the fully relaxed complex of protonated isopropylbenzene and benzene, n-propylbenzene formation cannot be expected on catalysts with nonrestricted reaction space. A constrained model confirmed the existence of a reaction pathway leading to n-propylbenzene formation, affirming experimental data.
