Реферат: According to the data from quantum-chemical calculations and theoretical analysis, the effect of fluorine atoms on the electronic and stereochemical structure of the benzyl radical depends substantially on their position. Fluorine atoms in the ring hinder the out-of-plane distortions of the CH2 group, and substituted C6F(n)H(5-n)-CH2 radicals are accordingly planar-pi-radicals. On the other hand, the presence of alpha-fluorine atoms assists pyramidal deformation of the methylene fragment, leading in the case of the alpha, alpha-difluoro-substituted compounds to the formation of nonplanar pseudo-pi-radical structures. Here the fluorine atoms in the ring at the p and o positions should increase somewhat while those at the m positions should reduce the capacity of the CF2 group for deformation.
