The expected mechanism of the Cl-initiated oxidation of C6F13CH2OH leading to the aldehyde C6F 13CHO is: Cl + C6F13CH2OH ^ HCl + C6F 13CHOH C6F C13 HOH + O2 ^ C6F 13CHO + HO2 C6F13CHO then reacts with Cl and could also be photolysed: C6F13CHO + Cl ^ C6F13CO + HCl C6F13CHO + hv ^ C6F13CO + H C6F13CHO + hv ^ C6F13 + HCO C6F13CO and C6F13radicals will ultimately lead to CF2O. nTehxetrsaetceticoonn)swtaenrtes oubsetadintoedfiattthWeuEpUpePrHtaOl RfoEr (ekx(pCelri+mCen6Fta1l3CprHo2fOileHs)toantdenkt(aCtilve+lyC6aFss1e3CssHtOhe)) (see importance of the photolysis of the aldehyde.
