Isolable C‐Phosphonio‐Boratavinyl Anion

Angewandte Chemie, EarlyView.
A persistent C‐phosphonio boratavinyl anion was successfully synthesized. This boron‐containing vinyl lithium, featuring a vinyl carbon with an excessively high negative charge, exhibits remarkable nucleophilic and basic character, which was demonstrated by the result of a rapid reaction with H2 at RT.

Introducing Diradicaloid Thiele's Hydrocarbon Derivatives as Ligand in Transition Metal Chemistry

Angewandte Chemie, EarlyView.
N‐doped Thiele's hydrocarbon derivative is introduced as a ligand for the synthesis of mono‐ and bimetallic rhodium complexes as well as cyclometalated iridium complexes. These compounds constitute the first metal complexes based on a Thiele's hydrocarbon (or p‐quinodimethane) derivative and, to the best of our knowledge, the first cyclometalated ...

Orchestrating Anion–π+ Interactions to Accelerate Metal‐Free Room‐Temperature Phosphorescence

Angewandte Chemie, EarlyView.
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...

[O─I─O]+ Halogen‐Bonded Complexes of Pyridine N‐Oxides

Angewandte Chemie, EarlyView.
The missing puzzle of 3‐center‐4‐electron halogen‐bonded complexes viz. [O─I─O]+ of pyridine N‐oxides are structurally characterized by x‐ray diffraction. Monodentate N‐oxide O‐atom acts as the halogen bond acceptor. Their solution complexations are characterized by 15N NMR spectroscopy.
