|Title:||Gaseous Sf3 +: An Efficient Electrophilic Monofluorinating Agent For Five-membered Heteroaromatic Compounds|
|Abstract:||Reactions of gaseous SF3 + ions with furan, thiophene, pyrrole, and several of their alkyl derivatives were performed via MS2 experiments and found to occur readily both by electron abstraction and F+ transfer. Then, by performing MS3 experiments, the F+ transfer products - the protonated monofluorinated molecules - were mass-selected and deprotonated by a second reaction with a stronger base. F+ transfer from gaseous SF3 + followed by deprotonation promotes therefore C-H by C-F replacement in five-membered heteroaromatic compounds and the efficient gas-phase synthesis of their neutral monofluorinated derivatives.|
