Original Abstract

Molecular modelling represents a powerful tool enabling to predict new compounds, particular properties and subsequently to interpret the experimental data. To confirm the behaviour of N-heterocyclic carbenes and their chloride precursors selected characteristics of a molecule were investigated. The calculation of significant molecular orbitals and electrostatic potential maps was made. Subsequently, bond distances and bond angles of representative imidazole and imidazoline compounds and from them prepared free carbenes were obtained by using computer programs. Data of structural similar compounds, which have been already characterized, were obtained from CCDC (Cambridge Crystallographic Data Centre) and were compared with the calculated data. Subsequently, the mechanism of the ring-opening polymerization of lactide was investigated. Based on calculated energies of all stationary points the novel approach of chain-end-activated mechanism was suggested.
