Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor
Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

A Combined MS/MS and IMS Study Into the Fragmentation Pathway of Nifedipine
Journal of Mass Spectrometry, Volume 61, Issue 7, July 2026.ABSTRACT Collision‐induced dissociation (CID) of small molecules, typically with a molecular mass below 1500 Da, is widely applied for the structural identification of drug metabolites, synthetic by‐products and unknown compounds. Nonetheless, the interpretation of MS/MS spectra derived from protonated or sodiated molecules mainly relies on the ...

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.Two reaction pathways, Paths 1 and 2, are involved in H2O2 activation by Cu complexes with N3‐tridentate ligands, depending on the ease of bridging structure formation. In Path 1, hydroxy radical (HO•) is formed from a hydroperoxo Cu(II) intermediate. In Path 2, a relevant complex‐based μ‐O• bridged Cu(II)2 active species is formed from a bis‐μ‐oxo Cu ...

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...
