Gold(III) Semiquinone Complexes: Synthesis, Structure, and Application in Photocatalysis
Angewandte Chemie, EarlyView.Au(III) catecholate complexes engage into electron donor acceptor (EDA) interactions with aryldiazonium salts, enabling single‐electron transfer under green light irradiation. Ligand‐centered one‐electron oxidation to stable semi‐quinone complexes provides a new platform for standalone Au(III) photoredox catalysis, as substantiated by the C–H arylation

Hydroxymethylfurfural: an indicative parameter of heat damage in cereal products
Czech Journal of Food Sciences, 2004 The main chemical changes occurring during biscuit cooking result from two complex reactions involving reducing sugars: the Maillard reaction and caramelisation, both of them being responsible for non enzymatic browning.

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst
Chemistry – A European Journal, EarlyView.While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Main‐chain polyfullerenes: Taking fullerene to the next dimension
Polymer International, EarlyView.This short review appraises main‐chain polyfullerenes. Their slow development over 30 years has suddenly boomed with a rapid growth due to exciting developments in solar energy. Abstract This mini‐review gives an overview of the development, chemistry, properties and applications of main‐chain polyfullerenes.

Rapid Communications in Mass Spectrometry, EarlyView.ABSTRACT Rationale To increase the confidentiality level of molecular tags, binary information can be hidden in sequence‐defined oligomers using isobaric monomers including a photo‐sensitive one, which mass can be modified upon light irradiation. Reading such secured data requires light edition prior to MS/MS sequencing, which was investigated here in ...
