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.

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.
