From the potential energy profile, it can be predicted that, the dominant channel of this reaction consists of three steps: the two reactants first form a three-membered ring intermediate (INT1) through a barrier-free exothermic reaction of 19.2 kJ/mol; three-membered ring intermediate (INT1) isomerizes to a four-membered ring silylene(P2) via the transition state (TS2) with an energy barrier of 22.8 kJ/mol; four-membered ring silylene(P2) further reacts with ethene(R2) to form a silicic bis-heterocyclic compound (P3), which is also a barrier-free exothermic reaction of 132.2 kJ/mol.
