H2O2 Activation and Alkane Oxidation by Copper Complexes With R‐dpa N3‐Tridentate Ligands: The Complex‐Based Dicopper Active Species as a Key Feature in the Efficient Alkane Oxidation

Chemistry – A European Journal, EarlyView.
Two reaction pathways, Paths 1 and 2, are involved in H2O2 activation by Cu complexes with N3‐tridentate ligands, depending on the ease of bridging structure formation. In Path 1, hydroxy radical (HO•) is formed from a hydroperoxo Cu(II) intermediate. In Path 2, a relevant complex‐based μ‐O• bridged Cu(II)2 active species is formed from a bis‐μ‐oxo Cu ...

Phosphorescence of Heavy, T‐Shaped Pnictogen Trisamides in Solution at Room Temperature in the Near‐Infrared II Region

Chemistry – A European Journal, EarlyView.
The unique photophysical properties of heavy T‐shaped Sb and Bi trisamides are reported. A ligand‐to‐pnictogen charge‐transfer excitation from a redox‐active NNN pincer to a vacant pnictogen p‐orbital populates a triplet state that emits in the highly desirable NIR‐II region, with lifetimes up to the µs range.

Cationic Sulfonium‐Based Tripodal Ligand and Its Rh(I) Complexes

Chemistry – A European Journal, EarlyView.
We report a cationic EP3‐type tripodal ligand based on an aromatic sulfonium cation (E = S+) along with a series of its Rh(I) complexes. Structural, spectroscopic, electrochemical, and computational analyses of these complexes compared to isostructural analogs (E = Si− or P) reveal pronounced electron density depletion at Rh in the sulfonium congener ...

Heteroatom‐Doped Graphdiynes and Their Applications in Photo‐/Electro‐Catalytic CO2 Conversion

Carbon Innovation, EarlyView.
This review highlights the versatile role of doped graphdiyne (GDY) in boosting CO2 conversion, where metal and non‐metal doping simultaneously tune the electronic structure, create abundant active sites, and improve charge separation, light harvesting, and CO2 adsorption.

Hydrogen Atom Transfer: An Intramolecular Main‐Group Metal‐Ligand Cooperative Biradical Pathway

Chinese Journal of Chemistry, EarlyView.
The molecular system consisting of a main‐group metal and a redox‐active ligand, ((2,6‐iPr2C6H3)NC(Me))2AlCl(THF), has been shown to react with azides and diazomethanes, yielding products through both a biradical intermediate and a hydrogen atom transfer process.
