Cross Carbonyl‐Olefin Metathesis of Unactivated Olefins

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
A method for the olefination of aryl aldehydes with unactivated alkenes via cross carbonyl‐olefin metathesis is described. Reaction of an aldehyde substrate with a cis−1,2‐disubstituted or monosubstituted olefin using the HBF4 salt of 2,3‐diazabicyclo[2.2.2]octane results in high‐yielding olefination with exclusive trans stereoselectivity. The reaction

Together We Are Stronger: An Unexpected Synergistic Effect During Anionic Ligand Exchange in Ruthenium Olefin Metathesis Catalysts

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
Combining dichloro and diiodo ruthenium catalysts produces mixed chloro–iodo species via in situ halide exchange, resulting in a new, more efficient catalytic system. The mixed catalysts outperform their homo‐anionic counterparts, delivering enhanced activity, higher conversion, and strong suppression of isomerization under both thermal and ...

The Versatile Structural World of Methanedi‐ and Trisulfonic Acid and Their Salts

open access: yesChemistryOpen, Volume 15, Issue 7, July 2026.
The solid‐state structures of the CH4‐derived polysulfonic acids methanedisulfonic acid (MDSA) and methanetrisulfonic acid (MTSA) are presented for the first time. Additionally, a broad overview over possible MDS and MTS salts, containing mostly group I cations, is given and their solid‐state structures are analyzed, showing the structural versatility ...

Morphological Control of Aurophilic Chains of Gold(I) Dithiolate Dimers With Alkali and Alkali Earth Cations

open access: yesChemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
Luminescent coordination polymers of Group 1 (Li, K, Cs) and 2 (Mg─Ba) cations with gold(I) iso‐maleonitriledithiolate ({Au2[S2C = C(CN)2]}2−) units were prepared; 1‐D aurophilic chains are present in all cases. The structures strongly depend on cation charge and size, with N‐cyano coordination observed in the Gp 1 and larger Gp 2 cations. Increasingly

Merging Biocatalysis and Chemocatalysis in Flow: State‐of‐the‐Art and Future Directions for Sustainable Synthesis

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
This review highlights recent advances in integrating biocatalysis and chemocatalysis in continuous flow to create streamlined, sustainable processes. It examines chemo‐enzymatic cascades combining at least one enzymatic and one chemical step, discusses challenges such as enzyme immobilization, leaching, and reactor clogging, and presents solutions ...
