The correlation of the reactive component of the bimolecular quenching rate constant, k r , with DG for reactions of singlet molecular oxygen with phenols is interpreted in terms of classical and semiclassical theories of electron transfer. Both treatments indicate a diabatic process with a reorgani

β¦ Synopsis
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 results are wholly colnpatible with observation

Dedicated to Professor AndreΓ M. Braun on the occasion of his 60th birthday a-Methylstyrene (1) was photo-oxidized in the presence of a series of alkylated dimethoxybenzenes as sensitizers in an oxygen-saturated MeCN solution to afford the cleaved ketone 2, epoxide 3, as well as a small amount of th
The oxidation of cis-l,4-polybutadiene by molecular oxygen, singlet oxygen, atomic oxygen and ozone has been studied using u.v. and i.r. spectroscopic methods. Some possible implications of the results of oxidation in the presence of singlet oxygen (parallel free radical oxidation) and atomic oxygen
The kinetics and mechanism of the gaseous reaction of vinyl radicals with molecular oxygen have been studied at 296 K. The products formed are HCO and H2C0. The rate constant is 1.0 X 10-r' cm3 molecule-' s-\* and is independent of pressure between 0.4 and 4 Torr.
