Resumen:
The temperature dependences of the rate coefficients of the gas-phase reactions of O(3P) atoms with CH2=CHCH2Cl and CH2=CClCH3  were studied in the range 298–359 K, using the discharge flow-chemiluminescence technique. The Arrhenius expressions obtained (in units of cm3 molecule-1 s-1) were: k1=(1.96 ± 0.33) x 10-10 exp [(-1476 ± 56) / T] and k2=(9.11 ± 0.17) x 10-11 exp [(-1007 ± 61) / T] with Ea in J mol-1. Theoretical calculations at different levels of theory were carried out. Both, theoretical and experimental results, supports the conclusion that addition of O (3P)  to the less substituted carbon atom of the double bond of the studied chloropropenes, is the main pathway of the reactions.
