“…This may be because of the increase of negative charge at the carbon atom as suggested some time ago by Cvetanovic. , This might reduce the already small activation energy. Buchta et al and Cvetanovic have shown that the ionization potential of the alkene is strongly correlated with the activation energy. , …”

“…Buchta et al and Cvetanovic have shown that the ionization potential of the alkene is strongly correlated with the activation energy. 11,12 An alternate possibility is that the extra vibrational modes absorb the energy released on attachment of the O atom. The O atom is attracted to a deep well in the C-O coordinate but unless some energy can be rapidly transferred to other modes, the O atom will bounce off.…”

The kinetics of the reactions of ground state oxygen atoms with 1‐pentene, 1‐hexene, cis‐2‐pentene, and trans‐2‐pentene was investigated in the temperature range 200 to 370 K. In this range the temperature dependences of the rate constants can be represented by k = A′ Tn exp(− E′a/RT) with A′ = (1.0 ± 0.6) · 10−14 cm3 s−1, n = 1.13 ± 0.02, E′a = 0.54 ± 0.05 kJ mol−1 for 1‐pentene: A′ = (1.3 ± 1.2) · 10−14 cm3 s−1, n = 1.04 ± 0.08, E′a = 0.2 ± 0.4 kJ mol−1 for 1‐hexene; A′ = (0.6 ± 0.6) · 10−14 cm3 s−1, n = 1.12 ± 0.05, E′a = − 3.8 ± 0.8 kJ mol−1 for cis‐2‐pentene; and A′ = (0.6 ± 0.8) · 10−14 cm3 s−1, n = 1.14 ± 0.06, E′a = − 4.3 ± 0.5 kJ mol−1 for trans‐2‐pentene. The atoms were generated by the H2‐laser photolysis of NO and detected by time resolved chemiluminescence in the presence of NO. The concentrations of the O(3P) atoms were kept so low that secondary reactions with products are unimportant. © 1997 John Wiley & Sons, Inc.

The kinetics of the reactions of CH2 (X̄3B1) with selected alkenes R = ethylene (1), tetramethylethylene (2), cycloheptatriene (3), and 1,3‐butadiene (4) were studied at temperatures between 296 K≤T≤728 K. Rate constants were measured for reactions (2–4) using the discharge flow technique with Far‐Infrared Laser Magnetic Resonance (FIR–LMR) detection of 3CH2. The experimental data can be described by the rate expressions (±2σ) These data and results for reaction (1) obtained earlier were analyzed to separate the contributions to the CH2 (X̄) depletion by reactive channels versus collisional excitation to the ã1A1 state of CH2 followed by reactions of CH2 (ã). The rate expressions (±2σ) for the reactive pathways of CH2 (X̄) were found to be .
