Square‐Planar Ruthenium Alkylidyne Complexes Undergo Stepwise Rather Than Concerted [2 + 2] Cycloadditions with Alkynes

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
After decades of research into metal alkylidyne complexes and their extensive use as catalysts for alkyne metathesis, one might think that there is nothing fundamentally new to be discovered in this field. The present study into formally d4‐configured Ru alkylidynes shows that this notion is incorrect: not only is a novel and convenient entry route ...

Triplet Metallovinylidenes of Palladium and Platinum Based on a Chelating P/Diazoalkene Ligand

Angewandte Chemie International Edition, Volume 65, Issue 1, 2 January 2026.
A new class of chelating diazoalkenes is presented and their coordination complexes with Pd and Pt are characterized. Irradiation triggers N2 loss and gives access to the first triplet metallovinylidenes spectroscopically characterized utilizing FD‐FT THz‐EPR spectroscopy and SQUID measurements.

Ring Strain‐Promoted Activation of Pyridines by a Saturated BSi2 Cycle

Angewandte Chemie International Edition, Volume 65, Issue 1, 2 January 2026.
We report a highly strained boratadisilirane with the elusive anionic BSi2 ring motif. Cleavage of the Si─Si bond during reactions with pyridine derivatives activates them in three different ways: 1) for pyridine itself selective ortho‐CH activation and concomitant hydrogen transfer to a second pyridine molecule occurs, 2) with dimethylaminopyridine ...
