Dihydrogen transfer reactions. An SCF-MO study of the relative energies of the concerted and stepwise pathways
Abstract
Semi-empirical SCF-MO calculations for a variety of reactions involving dihydrogen transfer to a π bond predict that the energy difference between the concerted pericyclic and the stepwise radical pair pathway is relatively insensitive to structural variation in the π bond, and indicate that the concerted route is favoured more by the AM1 than by the MNDO procedure.
