On the chain length effect: Comparative reactivity of a macroradical and a radical
Lalevée,Allonas,Fouassier
, p. 227 - 230 (2009)
The reactivity of two aminoalkyl radicals formed from ethyldimethylaminobenzoate (EDB) and a polymeric derivative (PoEDB) toward different additives such as oxygen, TEMPO, methylacrylate MA, phenols, an onium salt, CBr4 is investigated through
Halogen abstraction reaction between aminoalkyl radicals and alkyl halides: Unusual high rate constants
Lalevée,Allonas,Fouassier
scheme or table, p. 415 - 418 (2009/02/02)
The very high reactivity of aminoalkyl radicals toward the halogen abstraction reaction is reported for the first time. Reaction rate constants with CCl4 and CBr4 are close to the diffusion limit: they are about 4-5 orders of magnitude higher than those previously determined for typical alkyl radicals. A better understanding of this unusual behavior is obtained using molecular orbitals (MO) calculations. The participation of polar effects is directly evidenced. This approach can be useful for the design of new reducing agents.
FTIR and computational studies of gas-phase hydrogen atom abstraction kinetics by t-butoxy radical

By using Fourier-Transform Infrared (FTIR) absorption spectroscopy, rate coefficients in the range of 10-16 to 10-14 cm3 molecule-1 s-1 have been determined for the hydrogen atom abstraction reactions of several substrates including halogenated organic compounds and amines by t-butoxy radical generated from the uv photolysis of t-butyl nitrite in the gas phase. Arrhenius parameters for selected reactions have been measured in the temperature range 299-318 K. Transition states and activation barriers for such reactions have been computed with the help of Gaussian 03 software and found to match very well with the experimental values.
