Реферат: The reaction of [2.2]paracyclophane with nitrosonium tetrachloroaluminate was studied by NMR (H-1, C-13) spectroscopy using deuterium isotopic perturbation technique. The resulting cationic complexes containing one and two nitrosonium ions are involved in fast (on the NMR time scale) interconversion. Quantum-chemical calculations performed on the DFT level (using triple zeta basis set) indicate the higher stability of 2 eta single-charged pi-complexes relative to sigma complexes corresponding to the addition of NO+ ion at the ipso and ortho positions. The formation of the single-charged pi-complex is energetically more favorable, compared to the double-charged pi-complex. The affinity of NO+ for [2.2]paracyclophane is much greater than for p-xylene, presumably due to stacking interaction between the aromatic rings in the pi-complex.
