摘要：

In a series of structurally similar alkyl radicals 1 a - c the tertiary 1,1-dimethyl-5-hexenyl radical 1c reacts 30 times faster with carbon tetrachloride than the primary 5-hexenyl radical 1 a. The reactivity of the secondary 1-methyl-5-hexenyl radical 1 b aligns itself in between the primary and the tertiary radical la and 1c. The results indicate that the increasing nucleophilicity of the alkyl radicals is the major factor contributing to the reactivity.
