Abstract: Methods of quantum mechanics and their research applications on the mechanism of benzene alkylation with short-chain olefins in recent years were reviewed. Software based on quantum mechanics and their applications were also introduced. The controversial concerted and stepwise mechanism on the alkylation between benzene and short-chain olefins was elaborated by different model sizes and variable computational methods. The future of computational method for research on the mechanism of benzene alkylation with short-chain was also discussed. The hybrid QM/MM (quantum mechanics/molecular mechanics) approach that combines the strengths of the QM (accuracy) and MM (speed) approaches will be a more effective way to study chemical reaction mechanism.

Key words: quantum mechanics, benzene, short-chain olefins, alkylation, reaction, model
