Experimental and DFT Study of Azo-bis-Cyanuric Chloride Polar Diels-Alder Reaction with a Number of Dienes. Ways of Further Modification of the Obtained Products

The reaction of azo-bis-cyanuric chloride as strong electrophilic aza-dienophile in Diels-Alder cycloaddition with a number of dienes of different nucleophilicity, namely 2,3-dimethylbutadiene, 2-methylbutadiene and 1-acethoxybutadiene, was carried out and computationally analyzed on B3LYP/6-31G(d,p) level. Local and global reactivity indices, based on FMO theory, as well as TS geometries and activation energies were calculated. Reaction proceeds rapidly with high yields and in mild conditions. Ways of products further modification by chlorine atoms substitution were also studied.

The quantum-chemical modelling of structure and spectral characteristics for molecular complexes in pentaplast-terlon system

Using ab initio methods of quantum chemistry, structure and spectral properties of the molecular complexes which were formed by monomer of pentaplast chain and N-phenylbenzamide, that recreate features of intermolecular interaction in the penton-terlon system were researched. Offered theoretical models reflect proper spectral and energetic characteristics of investigated system
