Abstract: A quantum chemical study of cationic polymerization monomer protonation of p-methylstyrene (in the presence of complex catalyst - boron fluoride/water in toluene - with stoichiometric composition of mixture 1:1:1) by ab initio method was first performed. It was found that the activation energy of this reaction is 136 kJ/mol, and the thermal effect is 116 kJ/mol.
Keywords: n-methyl styrene, protonation, boron fluoride/ water catalyst, toluene, reaction heat, ab initio method.
Introduction
Until now, a number of important fundamental questions remain concerning the course of elementary
acts of cationic polymerization of p-methylstyrene in the presence of a complex catalyst
which is often used in practice as an indifferent solvent, remain [1]. Therefore, the object of this
work is to study the protonation procedure of p-methylstyrene in the presence of this complex
catalyst.
Methodology
The protonation of cationic polymerization monomer of p-methylstyrene in the presence of a complex catalyst BF3∙H2O in toluene (with a stoichiometric composition of the mixture 1:1:1, respectively), was studied. The distance between the C(1) and H(20) atoms was chosen as the reaction coordinate. The calculation was performed using ab initio RHF/6-311G** quantum-chemical method [2] with geometry optimization for all parameters by the gradient method integrated into Firefly program [3], based on GAMESS source code [2, 4]. This method was chosen because it allows you to accurately calculate the reaction energy barriers and active centers (AC) [4]. The calculations were performed within the framework of molecular model and isolated molecule in toluene according to technique described in detail in [5] and applied in [6-19]. For visual molecular representation the MacMolPlt program was used [10].
Calculation data
The changes in bond lengths along the interaction coordinate, valence angles and atomic charges of molecular system during protonation reaction of p-methylstyrene in the presence of BF3∙H2O catalyst in toluene (the stoichiometric composition 1: 1: 1) are presented in Tables 1-3.

Fig. 1 presents the geometric and electronic structure of initial model of p-methylstyrene,
in Fig. 2 - the structure after interaction of catalyst with p-methylstyrene, Fig.
3 – the energy profile of this interaction, Fig. 4 – the changes in charges on atoms directly involved
in interaction of complex catalyst BF3·H2O with p-methylstyrene.
The atoms C(1), C(2), H(20), O(21) and B(23) are directly involved in this interaction. Let us analyze the change in charges on these atoms along the reaction coordinate.
At coordination stage (1st stage, steps 1-7), the charge on the C(1) atom changes from -0.219 to -0.254; at the stage of active center formation (2nd stage, steps 8-17) - from -0.266 to -0.358; at the stage of final product formation (3rd stage, steps 18-21) - from -0.361 to -0.262.
At 1st stage, the atomic charge on C (2) changes from -0,098 to -0,108; at 2nd stage - from 0,332 to 0,359; at 3rd stage - from -0,080 to 0,081.
At 1st stage, the atomic charge on H(20) changes from 0,325 to 0,329; at 2nd stage - from -0,104 to -0,100; at 3rd stage - from 0,360 to 0,213.
At 1st stage, the atomic charge on О(21) changes from -0,437 to -0,438; at 2nd stage - from -0,438 to -0,453; at 3rd stage - from -0,467 to -0,613.
At 1st stage, the atomic charge on B(23) changes from 0,820 to 0,818; at 2nd stage - from 0,819 to 0,794; at 3rd stage - from 0,790 to 0,809.
The charges on toluene atoms (C(27) -C(33) and H(33) -H(40)) along the reaction coordinate varied in the following ranges: for C(27) -C(33): from -0.176 to -0.119; for H(33)-H(40): from 0.139 to 0.123. During of reaction, the O(21)-H(20) bonds are simultaneously broken, the C(1) -C(2) changes from double π-bond to a single σ-bond, the new bond C(1) - H(20) and the counterion [BF3∙OH] is formed (Fig. 2).
The values of activation energy and thermal effect are calculated, equal to 136 kJ/mol and 116 kJ/mol, respectively.
Thus, the changes in atomic charges, behavior of reaction fragments, breaking and formation of new bonds in the reaction under study indicate that it proceeds according to the scheme of coordinated interactions.
