, p. 3296 - 3300 (1984)
The kinetics of the photolysis-induced free-radical reaction in carbon tetrachloride solution of cyclohexane in the absence and in the presence of oxygen were studied in the temperature range of 100-200 deg C.It was found that the influence of the oxygen on the chloroform formation is significant, and a new mechanism which explains the results was suggested.The rate constants for the reactions .CCl3 + O2 -> .CCl3O2 (k6), .CCl3O2 -> COCl2 + ClO (k7), and .CCl3O2 + C6H12 -> CHCl3 + .C6H11 + O2 (k8) were found as log (k6/(M-1s-1)) = 5.05 +/- 0.07 and log 8/k7)/(M-1s-1)> = (3.0808 +/- 0.0973) - (3.7080 +/- 0.1857)/θ, where θ = 2.303RT kcal/mol.
The reaction of O(3P) with cyclohexane clusters
Rudich, Y.,Hurwitz, Y.,Lifson, S.,Naaman, R.
, p. 2936 - 2940 (1993)
The effect of cluster formation on the reactivity of cyclohexane was investigated.When single molecules react with O(3P) the products are the OH radical and cyclohexyl radical.In contrast, we found that when small clusters react with O(3/

Rate constants for the reactions of the NH//2(X**2B//1) radical with ethane, propane and cyclohexane were measured in an isothermal flow system. Kinetic data were obtained at 4 mbar helium pressure in the high temperature range given below. left bracket NH//2 right bracket (t)-profiles were mapped at pseudo-first order conditions left bracket NH//2 right bracket //0 VM LS TH left bracket RH right bracket //0 with the laser induced fluorescence technique. The temperature dependence of the rate constants is represented by certain Arrhenius-expressions. A correlation of the activation energy with the energy of the broken C-H bond of various hydrocarbons is discussed.

Chemistry of the t-butoxyl radical: Evidence that most hydrogen abstractions from carbon are entropy-controlled

Absolute rate constants and Arrhenius parameters for hydrogen abstractions (from carbon) by the t-butoxyl radical (tBuO·) are reported for several hydrocarbons and tertiary amines in solution. Combined with data already in the literature, an an
Absolute rate constants for some reactions of the triethylamineboryl radical and the borane radical anion

Laser flash photolysis (LFP) of dj-tert-butyl peroxide or dicumyl peroxide at ambient temperatures in the presence of Et3N→BH3 or BH4- generated the title radicals which were found to have broad, featureless absorptions in the visible region. Rate constants for H-atom abstraction from Et3N→BH3 by cumyloxyl radicals show a small solvent dependence, e.g. 12 × 107 and 2.2 × 107 dm3 mol-1 s-1 in isooctane and acetonitrile, respectively. Rate constants for halogen atom abstraction by Et3N→BH2. and BH3.- from a number of chlorides and bromides were determined by LFP and by competitive kinetics, e.g., for Et3N→BH2. + CCl4/PhCH2Cl/CH3(CH2)2Cl, k = 4.4 × 109/1.1 × 107/5.1 × 105 dm3 mol-1 s-1 and for BH3.- + CCl4/PhCH2Cl, k = 2.0 × 109/3.0 × 107 dm3 mol-1 s-1. Rates of addition of Et3N→BH2. to 1-and 1,1-substituted olefins increase dramatically as the electron affinity of the olefin increases, confirming the nucleophilic character of amine-boryl radicals. A comparison of the present results with literature data for the addition of olefins of four nucleophilic carbon-centered radicals proves that Et3N→BH2. is by far the most nucleophilic radical for which kinetic data are available. A few rate constants for abstraction of hydrogen from electron-deficient carbon by Et3N→BH2. are also reported.
