Abstract: The dicationic 4-ammonio-substituted imidazolium salt (2·H)(OTf)2 is readily obtained from its 4-amino-substituted imidazolium precursor (1·H)(OTf) by methylation of the exocyclic nitrogen. The cationic NHC (2)(OTf) is generated in situ by deprotonation of (2·H)(OTf)2 with 1… read more here.
