Multi‐Solvent Suppression Ultrafast 2D COSY for High‐Throughput Wine Screening
Magnetic Resonance in Chemistry, EarlyView.An interleaved ultrafast COSY with multi‐solvent suppression was developed for wine analysis to overcome limitations often associated with 1D 1H NMR (signal overlap) and conventional 2D NMR (long acquisition times) methods. Within an acquisition time of ~20 min, it revealed hidden metabolite peaks and cross peaks for improved annotation and ...

FeCl3‐Catalyzed Synthesis of Ynones from Silylated Alkynes and Acetic Anhydride
ChemistryOpen, EarlyView.The synthesis of alkynones from silylated alkynes and acid chlorides, first reported by Birkhofer in 1963, remains a valuable transformation. However, its reliance on stoichiometric AlCl3 and corrosive reagents raises environmental and practical concerns. To address this, a greener protocol using catalytic FeCl3 and acetic anhydride is developed.
