Unlocking Stereodefined Olefins by Z‐Selective Transition Metals‐catalyzed C−H Activations

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
The synthesis of Z‐olefins is an important challenge in synthetic organic chemistry. Within this review, we report a comprehensive overview of transition metals‐catalyzed Z‐selective C–H activations of (hetero)arenes for the synthesis of stereodefined olefins.

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...

Triazole‐Bridged Dinuclear Ru(II) and Ir(III) Complexes: Photophysics, Electrochemistry, and DFT/TD‐DFT Analysis

ChemistrySelect, Volume 11, Issue 25, 3 July 2026.
Investigations of a click‐built heteroditopic triazole–bipyridyl bridge (L3) and its coordination to Ru(II) and Ir(III) centers are presented as a modular route to dinuclear luminophores and structure–property correlations. ABSTRACT The heteroditopic 1,2,3‐triazole ligand 4‐[4‐(pyridin‐2‐yl)‐1,2,3‐triazol‐1‐yl]‐2,2′‐bipyridine (L3), prepared here ...

Rhodium(I)‐Catalyzed P(III)‐Directed C–H Alkylation of Biarylphosphines With Maleimides

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
A Rh(I)‐catalyzed P(III)‐directed ortho‐C–H bond alkylation of biarylphosphines with maleimides is disclosed. The reaction accommodates substituted alkenes, proceeds efficiently on gram scale, and consistently generates diastereomeric phosphines. NMR and mechanistic studies reveal that the stereochemical outcome arises from conformational restriction ...
