Abstract

The protonation of ammonium ions NR4+ (R= H, CH3) to form the corresponding protioammonium dications HNR42+ (R= H, CH3) was investigated by hydrogen/deuterium exchange experiments and by ab initio molecular orbital calculations. Hydrogen/deuterium exchange was observed by 2H NMR spectroscopy at the CH3 groups of tetramethylammonium ion N (CH3) 4+ when reacted with excess DF: SbF5 superacid. On ...
