Mechanism of Interaction of Nitro Compounds with Olefins in Acetonitrile

Abstract

The interaction of 4-fluorostyrene with 4-CN-PhNO₂ in the presence of various solvents has been simulated by quantum chemistry methods. The reaction mechanism and activation barriers of its stages are proposed. The software package Gaussian03 was used for calculations. The optimal geometric parameters of the structures under study were obtained by means of the DFT/WB97XD/DGDZVP2 methods, the TD-SCF/DFT/WB97XD/DGDZVP2 and TD-SCF/DFT/PBEPBE/6-311g++(3d2f,3p2d) methods were used to calculate excited singlet and triplet states, and the IEFPCM model was employed to account for the solvent effects. The transition states were calculated by the TS method using the DFT/PBEPBE/6-311g++(3d2f,3p2d) method.

期刊介绍： High Energy Chemistry publishes original articles, reviews, and short communications on molecular and supramolecular photochemistry, photobiology, radiation chemistry, plasma chemistry, chemistry of nanosized systems, chemistry of new atoms, processes and materials for optical information systems and other areas of high energy chemistry. It publishes theoretical and experimental studies in all areas of high energy chemistry, such as the interaction of high-energy particles with matter, the nature and reactivity of short-lived species induced by the action of particle and electromagnetic radiation or hot atoms on substances in their gaseous and condensed states, and chemical processes initiated in organic and inorganic systems by high-energy radiation.
