Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

An Experimental and Theoretical Investigation of the Ethylene Oligomerization Reactions Catalyzed by Heterocyclic (Pyrazolyl)Imine Fe(II) and Co(II) Complexes

European Journal of Inorganic Chemistry, EarlyView.
Monometallic iron(II) and cobalt(II) complexes derived from potential hemilabile heterocyclic (pyrazolyl)imine catalyze ethylene oligomerization reactions upon activation with either EtAlCl2 or MAO to give predominantly butenes and hexenes. The catalytic activities are largely controlled by the complex structure and stabilization from the coordinated ...

Variable Coordination of Peroxide in a Dinuclear Copper Mono‐Oxygenase Model Complex Supported by a Pyridazine‐Bridged Ligand

European Journal of Inorganic Chemistry, EarlyView.
Variable coordination of peroxide: The reaction of the Cu(I) complex‐based on the BPMPD ligand with O2 at low temperatures initially led to a μ‐1,2 peroxo species (Cu2O2). By addition of an acid (lutidinium triflate), this species can be reversibly converted into a μ‐1,1‐hydroperoxo complex, which is monitored using UV/Vis spectroscopy and X‐ray ...
