Absolute rate constants for the addition of the 2-cyano-2-propyl radical to 26 alkenes CH2 = CXY at 315 K were determined in solution by time-resolved electron-spin-resonance spectroscopy. They vary with the alkene substituents from 30 M-' s-l to 7'010 M-' s-'. For styrene the temperature dependence
Absolute rate constants for the addition of the 2-hydroxy-2-propyl radical to 18 substituted alkenes (CH2 = C X Y ) were determined at (296 -+ 1) Kin 2-propanol by time-resolved electronspin-resonance spectroscopy. With alkene substitution the rate constants vary by more than 6 orders of magnitude.
