Recombination Reactions

The recombination reactions of arylaminyl radicals are studied on the basis of its order P\10 treatment, assuming dimeric intermediates with C-N or C-C bonding modes. In the case of diphenyl aminyl radical the N -N recombination causes an increase in the T-bonding energy and should be most favourable for the low temperature reactions. Due to the low dissociation energy of the N-N bond, the C-N bonding is preferred in the high temperature reactions. It is found that the ortho- and para-additions are energetically more favourable than the meta addition, in agreement with π-SCF MO calculations and experimental results. The recombination of 2,2′-dinaphthyl aminyl radicals proceeds through C-C and C -N bonding, the 1,1′-bonding is most favourable. The PMO-results are parallel to those of the π-SCF MO calculations, providing another demonstration for the utility of this method.
