The products of Cl atom and OH radical initiated oxidation of CF3CF=CH2 were studied in 700 Torr of N-2/O-2 diluent at 296 +/- 1 K. The reactions of Cl atoms and OH radicals with CF3CF=CH2 proceed via electrophilic addition to the double bond. The reaction with chlorine atoms proceeds 56 +/- 5% via addition to the central carbon. The chlorine atom initiated oxidation of CF3CF=CH2 gives CF3C(O)F in a molar yield which is indistinguishable from 100% and independent of [O-2], and HC(O)Cl in a molar yield which increased from 30% to 59% as [O-2] was increased from 3 to 700 Torr. The OH radical initiated oxidation of CF3CF=CH2 gives CF3C(O)F as major product in a yield of 91 +/- 6%. The results are discussed with respect to the atmospheric chemistry and environmental impact of CF3CF=CH2. (C) 2007 Published by Elsevier B.V.
