WebJan 1, 1977 · Abstract. The chlorine atom sensitized oxidations of HCCl 3, HCF 2 Cl and HCF 3 were studied at 30 °C. The HCCl 3 and HCF 2 Cl oxidized in a long chain process in which the only oxidation products were CCl 2 O and CF 2 O, respectively. The quantum yields depend on the [HCX 3 ]/ ( Ia [M]) 1 2 values, with upper limits of 195 for ϕ {CCl 2 O ...
