Selective Catalytic Oxidation of Benzyl Alcohol to Benzaldehyde With Alkyl Allyl Carbonates and Pd(II) Allyl‐Amidinate

open access: yesHelvetica Chimica Acta, EarlyView.
A Pd(II) allyl‐amidinate complex catalyzes the selective oxidation of benzyl alcohols to aldehydes using allyl alkyl carbonates as tailored, mild oxidants. The carbonate reagent acts both as oxidant and in situ base, enabling chemoselective conversion and minimizing overoxidation under mild conditions.

Phosphoramidate and Silyl Amine Mediated Synthesis of Isocyanide Cyclopentadienone Iron Complexes

open access: yesHelvetica Chimica Acta, EarlyView.
Carbonyl ligands in cyclopentadienone iron complexes are replaced by isocyanide ligands without using free, malodorous isocyanides. The reaction takes place via an Aza‐Wittig‐type reaction starting from primary amines, employing either phosphoramidates or silyl amines as intermediate reagents.

Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...
