On Phosphatitanacycles

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Titanocene phosphinidenes react with terminal alkynes in formal [2 + 2] cycloadditions to give unsaturated [C2PTi] metallcycles. Diphosphene complexes in combination with aryl‐substituted alkynes react similarly to provide metallacyclopentenes. Titanocene‐phosphinidene and diphosphanediide (or diphosphene) complexes Cp2Ti(PMe3)PMesTer and Cp2Ti(P2Ar2) (

A New Kinetic‐Mechanistic Approach Towards Spectrophotometric Bioanalysis of 2‐Phenylethylamine as a Sympathomimetic Agent Using Sodium Isopropyl Xanthate

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT 2‐Phenylethylamine (2‐PEA), an aromatic biogenic amine, demonstrates significant physiological and toxicological effects on human health. A variety of conventional methods have been widely used for the determination of 2‐PEA. However, the necessity of complex sample preparation and high cost of instrumentation may pose challenges to their ...

Hydrogen‐Bonded Molecular Clusters Transform into Surface‐Passivated Fluorophores in Carbon Nanodots: Mechanistic Insight and Sensing Application Toward Bilirubin and Cu2+ Ions

open access: yesChemPhysChem, Volume 27, Issue 9, 14 May 2026.
The present study demonstrates the transformation of dual‐emissive H‐bonded molecular clusters of fluorophores into single emissive amorphous carbon nanodots and their structure‐property relationship in fluorescence‐based sensing of Bilirubin and Cu2+ ions. The present study aims to explore the origin of fluorescence in nitrogen‐doped carbon dots (NCDs)

Solvent‐Controlled Electrochemical Cyclization of Areneazo‐2‐(2‐nitro)propanes to Benzo[c]cinnolines

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Solvent‐mediated redox pathway control enables the first electrochemical cyclization of areneazo‐2‐(2‐nitro)propanes to benzo[c]cinnolines. Mixed solvent systems containing hexafluoroisopropanol (HFIP) and MeOH additives widen the redox potential gaps and stabilize diazonium intermediates via hydrogen bonding, favoring oxidative intramolecular ...
