摘要：

CW and kinetic ESR spectroscopy are applied to determine rate constants for the addition of the tert-butyl radical to acrylonitrile at room temperature in various solvents. They increase with increasing solvent polarity from 2.8.10(6) M-1s-1 for tetradecane to 10.2.10(6) M-1s-1 for acetonitrile. This solvation effect indicates a substantial charge-transfer in the transition state for the addition and supports previous notations of the nucleophilicity of tert-butyl. A comparison of tert-butyl with hex-5-enyl and methyl is also given.
