Novel Metallomacrocyclic Carboxamide Mn(II) Complexes as Efficient Catalysts for the Transfer Hydrogenation of Ketones

ChemCatChem, Volume 15, Issue 23, December 7, 2023., 2023
Dinuclear Mn(II) complexes based on carboxamide ligands form efficient catalysts in the transfer hydrogenation of a wide scope of ketone substrates at very low catalyst concentrations. The current Mn(II) catalysts are relatively stable and affordable, thus offer superior alternatives to the more established Mn(I) carbonyl complexes in the transfer ...

Chemoenzymatic Route toward a De Novo Enantioselective Total Synthesis of (S)‐Baclofen Based on Metal‐Catalyzed Hydroformylation and Enzymatic Transamination

ChemBioChem, Volume 26, Issue 15, August 22, 2025.
A unique chemoenzymatic synthesis route toward (S)‐baclofen is presented, which highlights a hydroformylation and biocatalysis step toward the synthesis of such a challenging β‐chiral amino acid. The shown methodology exhibits high conversions and enantiomeric excess and is transferable to other β‐chiral amines and amino acids.

Self‐Catalyzed Chemically Coalescing Liquid Metal Emulsions

Advanced Science, Volume 12, Issue 20, May 29, 2025.
A new type of liquid metal emulsion is developed that chemically activates and becomes electrically conductive under mild thermal stimulus. The activation mechanism occurs through a unique set of catalytic dehalogenation and chemical oxide etching reactions. These emulsions are 3D printable and exhibit high shape retention after being heated.

Hemiindigoids as Prominent Photoswitch Scaffolds

ChemPhotoChem, Volume 9, Issue 3, March 2025.
This review explores the synthesis, photophysical properties, and diverse applications of hemiindigoid photoswitches, a class of chromophores derived from indigo. With unique visible‐light responsiveness, high thermal bistability, and rapid, reversible switching, hemiindigoids present promising advances in photopharmacology, molecular solar thermal ...
