Abstract
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 CH 3(CH 2) 7ĊH 2, 1.2 × 10 9; (CH 3) 3C •, 7.6 × 10 8; C 6H 5ĊH 2, 4.9 × 10 8; C 6H 5Ċ(CH 3) 2, 1.2 × 10 8; (C 6H 5) 2ĊCH 3, 4.6 × 10 7. Arrhenius parameters have also been determined for the n-nonyl and benzyl radicals.
