Chemistry – A European Journal, EarlyView.In this work, the synthesis and characterization of novel π‐extended phenazine diimides is reported. The derivatives undergo differential reduction to a dihydrophenazine or Meisenheimer form depending on the reaction conditions employed. The outcome of this work highlights the paramount importance of structural design in determining the nature of the ...

N-1 regioselective Michael-type addition of 5-substituted uracils to (2-hydroxyethyl) acrylate
Beilstein Journal of Organic Chemistry, 2007 N-1 regioselective Michael-type addition of 5-substituted uracils to (2-hydroxyethyl) acrylate is presented. The reactions were performed in polar aprotic solvents and with avoidance of polymerization of acrylic substrate.

Chemistry – A European Journal, EarlyView.It is a challenge to improve the selectivity of high‐denticity ligands for Mg2+ over Ca2+. We show that in aryl‐alkynyl derivatives of APTRA, electron‐withdrawing substituents lower the binding affinity for Ca2+ more than Mg2+, making the ligand more selective for Mg2+.

It's a Gas: Bioconjugation With Vapor‐Phase Reagents
Chemistry – A European Journal, EarlyView.Gaseous reagents are an emerging class of bioconjugation reagents that can offer alternative selectivity paradigms for the construction of precise bioconjugates. A variety of both inert and highly reactive gases have recently been developed for bioconjugation use.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

A New Hybrid Solid/Solvating Sulfur Conversion for Energy‐Dense Lithium‐Sulfur Batteries
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A moderately solvating electrolyte (1M LiTFSI in methoxyacetonitrile) offers hybrid solid/solvating conversion of sulfur, combining fast conversion kinetics and lean electrolyte operation. To boost the practical energy density of lithium‐sulfur batteries, replacing conventional solvating electrolytes with sparingly solvating ones has shown promise by ...
