摘要：

The radical cation of 2,5-dimethyl-2,4-hexadiene is identified by ESR upon adsorption of thc parent molecule on activated H-mordenite. The same radical is observed when 2,3-dimethyl-1-butene or 2-methylpropene is adsorbed. This is clear evidence for highly specific dimerisation-fragmentation reactions of the primary radical cations in the zeolite at room temperature.
