Recent Advances in Intramolecular C─N Bond Formation for Pyrrolidine Synthesis
ChemistryOpen, Volume 15, Issue 6, June 2026.This review highlights synthetic advances (2013–2025) in intramolecular C─N bond formation for constructing the pharmaceutically relevant pyrrolidine core. The review is organized into five methodological clusters: 1) intramolecular alkene/alkyne amination; 2) tandem annulations, which involve C─N bond formation as the key step; 3) nucleophilic ...

European Journal of Inorganic Chemistry, Volume 29, Issue 15, 20 May 2026.The concept of scorpionate ligands has evolved significantly since the introduction of tris(pyrazolyl)borate. By integrating a biological supramolecular ligand scaffold with the classic scorpionate architecture, researchers have made notable strides in mimicking the active sites of nitrogenase and advancing homogeneous catalysis.

A New Micro-Subcarrier OFDM-Based Waveform for Delay Doppler Domain Communication
IEEE AccessThis paper presents a new OFDM based modulation scheme for communication in doubly dispersive channels. We call this Delay-Doppler OFDM (DD-OFDM). Our waveform has the same sparse-channel benefits as orthogonal-time-frequency-space (OTFS) modulation ...

Alkyl Bismuth Cations: Synthesis, Characterization, and Application as Z‐Type Ligands
Chemistry – A European Journal, Volume 32, Issue 18, 14 May 2026.Rare examples of alkyl bismuth cations [BiR2(SbF6)] are presented, including cyclopropyl ligands and a bismacyclic structure. The bismuth‐centered Lewis acids act as Z‐type ligands toward the electron‐rich platinum atom in [Pt(PCy3)2], generating a set of metal‐only Lewis pairs. The structural and spectroscopic properties of these rare types of bismuth

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