The open-chain trioxide CF3OC(O)OOOC(O)OCF3 is synthesised by a photochemical reaction of CF3C(O)OC(O)CF 3, CO and O2 under a low-pressure mercury lamp at -40°C. The isolated trioxide is a colourless solid at -40°C and is characterised by IR, Raman, UV and NMR spectroscopy. The compound is thermally stable up to -30°C and decomposes with a half-life of 1 min at room temperature. Between -15 and +14°C the activation energy for the dissociation is 86.5 kJ mol-1 (20.7 kcal mol-1). Quantum chemical calculations have been performed to support the vibrational assignment and to discuss the existence of rotamers.

CF3O2CF3 was photolyzed at 254 nm in the presence of CO in 760 torr N2 or air at 296 K in a static reactor. In N2, the products CF3OC(O)C(O)OCF3 and CF3OC(O)O2C(O)OCF3 were detected by FTIR spectroscopy. In air, the only observed products were CF2O and CO2 and a chain process, initiated by CF3O, was invoked for the conversion of CO to CO2. From both product studies, a mechanism for the CF3O initiated oxidation of CO was derived, involving the addition reaction CF3O2 + CO → CF3OC(O). The rate constant for the reaction CF3O + CO at 296 K at a total pressure of 760 torr air was determined to be k(CF3O + CO) = (5.0 ± 0.9) ± 10-14 cm3 molecule-1 s-1.
