We analyze the stereoselectivity of singlet oxygen-olefin reactions, concluding that a biradical peroxyl intermediate is involved and that experimental results are inconsistent with perepoxide intermediates. Recently Conia et al. ' have reported the results of a series of experiments on the reactio
On the basis of the spin-and space-symmetry conservation criteria proposed previously, the cyclo~~~ition reactions of singlet molecular osy~en toward olehs and the thermal decomposition of dioxclane are characterized with respect to the mechanistic feature (conctrted, zwitterionic or biradical). The
Arguments are presented which show that zwitterionic or diradical intermediates in the singlet oxygen-olefin ene reaction would lead to a prediction that geminal groups would be competitive in the C-H abstraction reaction. Isotope effect data available from previous studies clearly show that such is
