Abstract

Abstract: The reactivity features of radiolytically (" Co-prays) generated unsolvated trifluoromethyl cation CF3+ toward pyrrole, N-methylpyrrole, furan, and thiophene have been measured under conditions, ie 7 Torr of C2H4 added, ensuring depletion of concomitant radicalic processes. Experiments have been carried out at atmospheric pressure and in the presence of variable concentrations of a gaseous base (NMe,, 0-5 Torr). The mechanism ...
