The gas phase elimination kinetics of 2-bromopropene was studied over the temperature range of 571–654 K and pressure range of 12–46 Torr using the seasoned static reaction system. Propyne was the only olefinic product formed and accounted for >98% of the reaction. This product was formed by homogeneous, unimolecular pathways with high-pressure first-order rate constant k∞ given by the equation k∞ = 1013.47 ± 0.6 exp−208.2 ± 6.7 (kJ mol−1)/RT. The error limits are 95% certainty limits. The observed Arrhenius parameters are consistent with the four centered activated complex. The presence of methyl group on α-carbon lowers the activation energy by 41 kJ mol−1. © 2006 Wiley Periodicals, Inc. Int J Chem Kinet 39: 1–5, 2007
