Base‐Free Production of H2 by Dehydrogenation of Formic Acid Using An Iridium–bisMETAMORPhos Complex

Erase the base: An iridium complex based on a cooperative ligand that functions as an internal base is reported. This complex can rapidly and cleanly dehydrogenate formic acid in absence of external base, a reaction that is required if formic acid is to be exploited as an energy carrier (see scheme).
