Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Alkoxide‐bridged disilver cations react with dihydrogen to form hydride‐bridged cations, releasing free alcohol. Hydrogenolysis of neutral silver fluorides affords hydride‐bridged disilver cations as their bifluoride salts. These reactions proceed most efficiently when the supporting ligands are expanded N‐heterocyclic carbenes (NHCs) derived from 6‐ and 7‐membered cyclic amidinium salts. Kinetics studies show that silver fluoride hydrogenolysis is first‐order in both silver and dihydrogen.</p> </abstract>
