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

open access: yesChemSusChem, 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 ...

A Synthetic Journey Toward Functional N‐Amidophenyl‐Substituted Hexaaza[16]paracyclophanes

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
N‐amidophenyl‐substituted hexaaza[16]paracyclophanes can be synthesized via a convergent and efficient pathway, combining Ullmann and Buchwald–Hartwig coupling reactions. In accordance with simpler triarylamine molecules, these macrocyclic structures exhibit interesting light‐induced self‐assembling properties.
