This commmunication demonstrates the preparation, isolation, and full characterization of superelectrophilic salts based on amidinedications in organic solvent, as their triflate salts. These dications are highly activated toward regiospecific reaction with hydrogen gas under mild conditions in the presence of a metal catalyst (Pd/C), mimicking the behavior of the natural substrate, N5,N10-methen
