The reactivity features of radiolytically ( 60 Co γ-rays) generated unsolvated trifluoromethyl cation CF 3 + toward pyrrole, N-methylpyrrole, furan, and thiophene have been measured under conditions, i.e. 7 Torr of C 2 H 4 added, ensuring depletion of conccomitant radicalic processes. Experiments have been carried out at atmospheric pressure and in the presence of variable concentrations of a gaseous
