| Abstract: | The mechanism of 2+2] cycloaddn. of singlet oxygen to propylene was examined using MINDO/3 with the energy gradient technique. The total reaction path has been calculated using Fukui's intrinsic reaction coordinate theory. The reaction is predicted to take place via a peroxide intermediate. The interactions between reactants, the stereochem. path, and the dynamic electronic effects of substituents are discussed. |
