Abstract
The uB3LYP/6-311g++(d,p) method in the gas phase was used to simulate the reaction of ethylene with ortho, meta, para methylnitrobenzene, chloronitrobenzene, (CCl3)PhNO2, (CF3)PhNO2 in the T1 state, as well as determining the influence of the position of donor and acceptor substituents in the benzene ring on the activation energy of the reaction under study. It is established that during the reaction ethylene oxide and nitroso compound are formed.
