A Ruthenium‐(Ph‐BPE) Catalyst for Asymmetric Alkynylation of Fluoral: Enantioselection From 1 of 12 Fluxional Stereogenic‐at‐Ruthenium Complexes

Angewandte Chemie International Edition, Volume 65, Issue 30, 20 July 2026.
The first enantioselective alkynylations of aqueous fluoral are described. These processes are catalyzed by an iodide‐bound ruthenium‐(Ph‐BPE)‐catalyst; an octahedral metal complex that can exist as 12 diastereomeric‐at‐metal isomers. Calculations reveal that 2 of 12 stereoisomeric complexes account for 99.9% of the Boltzmann population and that ...

Alkaline‐Earth Metal Complexes Based on Tridentate β‐Diketiminate Ligands Bearing a Tethered Secondary Amine: Synthesis and Characterization

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 11, 16 July 2026.
Deprotonotion of a β‐diketiminate ligand with a tethered secondary amine resulted in highly stable heteroleptic complexes, but the formation of the dianionic ligand could not be achieved. The alkaline‐earth (Ae) metal chemistry of a β‐diketiminate (BDI) ligand with a bulky Ar‐substituent and a pendant amine arm was investigated. The ligand precursor HC[

A N,N′‐p‐Tolyl Substituted Diazadiene Ligand with a Dithienylethane Backbone in Hexacoordinated Group IV Tetrachlorido Complexes—Steric Repulsions Govern the Axial Chirality Mode

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 11, 16 July 2026.
The chelating imino groups in [MCl4(DADDTEthane)] (M = Ti, Zr, Hf) give rise to a planar five‐membered (‐N=C‐C=N‐)M metallacycle. The two thiophene rings of the ligand backbone reside in a noncoplanar arrangement concerning the metallacycle, giving rise to two chiral C–C axes in the ligand backbone.
