Cover Feature: Production of Dihydrogen Using Ammonia Borane as Reagent and Pyrazole as Catalyst (ChemPhysChem 17/2023)

The Cover Feature illustrates the reaction of ammonia borane catalyzed by pyrazole yielding dihydrogen and amino borane. The results point toward a catalytic cycle by which, at the same time, ammonia borane can initially store and then, through catalysis, produce dihydrogen. It could therefore represent an environmentally sustainable (metal-free) catalyst to efficiently extract dihydrogen from small B−N bonded molecules.
