Item Kinetic of the [2 +3] cycloaddition of Z-C-aryl-N-phenylonitrones with 1-bromo-1-nitroethene(Видавництво Львівської політехніки, 2011) Mikulska, Maria; Barański, AndrzejKinetic measurements of the [2+3] cycloaddition reaction between 1-bromo-1-nitroethene and Z-C-aryl-N-phenylnitrones were carried out. Kinetic studies proved that despite the high p-deficiency of the nitroalkene, the reactions proceed according to the concerted mechanism. This is evidenced in particular by the character of the Dimroth-Hammet correlation.Item Мolecular mechanism of Diels-Alder reaction between cyclopentadiene and E-2-arylnitroethenes in the light of DFT computational study(Видавництво Львівської політехніки, 2011) Socha, Jan; Jasiński, Radomir; Barański, AndrzejThe mechanism of the Diels-Alder reaction between cyclopentadiene and E-2-arylnitroethenes were examined using the B3LYP/6-31G(d) (PCM) algorithm. It was found, that on both, competition paths, the reaction proceeds according to a one-step mechanism.
