摘要：

Radiolytic generation of radical cations in xenon matrices containing electron scavengers is illustrated by studying the 1,1,2,2-tetramethylcyclopropane radical cation. Dilute and concentrated solutions of tetramethylcyclopropane in xenon without electron scavengers and neat tetramethylcyclopropane yielded neutral radicals upon γ-irradiation. Speculation on the mechanisms of radical formation is presented. The radical species observed in the γ-irradiation of neat tetramethylcyclopropane appears to be identical with the paramagnetic species observed in CF2ClCFCl2 above 120 K, suggesting that a neutral radical rather than the ring-opened distonic radical cation is observed in the CF2ClCFCl2 matrix. © 1990 American Chemical Society.
