The photochemical! y excited nitroxide, 1,1,3,3-tetramethylisoindolin-2-yloxyl (1*), abstracts primary, secondary or tertiary hydrogens from unactivated hydrocarbons including cyclohexane, isobutane and n-butane. The resultant carbon-centred radicals are rapidly and efficiently trapped by ground state nitroxide. Hydrogen abstraction from methane may also occur, but is masked by secondary photochemical reactions.

Radical clocks have been used to study the kinetics of the coupling of the nitroxyl radical 1,1,3,3-tetramethylisoindoline-2-oxyl (T) in cyclohexane or benzene with a variety of carbon-centered radicals including simple unhindered primary, secondary, and

A time-resolved, laser flash photolysis study of the reaction of a variety of carbon-centered radicals with Tempo (2,2,6,6-tetramethylpiperidine-N-oxyl) at room temperature is reported.Some of the radicals examined and the corresponding measured rate constants (M-1 s-1) are CH3(CH2)7CH2-radical, 1.2 * 109; (CH3)3C-radical, 7.6 * 108; C6H5CH2-radical, 4.9 * 108; C6H5C(CH3)2-radical, 1.2 * 108; (C6H5)2CCH3-radical, 4.6 * 107.Arrhenius parameters have also been determined for the n-nonyl and benzyl radicals.
Solvent Effects on the Reaction of t-Butoxy Radicals with Methyl Methacrylate
Grant, Richard D.,Griffiths, Peter G.,Moad, Graeme,Rizzardo, Ezio,Solomon, David H.
, p. 2447 - 2454 (2007/10/02)
Examination of the title reaction in a range of solvents shows that the ratio of hydrogen abstraction to t-butoxy radical addition increases with increasing solvent polarity.In several cases there is a competition between solvent and methyl methacrylate for reaction with t-butoxy radicals.The implications of these findings for polymer structure are discussed.
