Strong Implications From Small Deviations in Labeling Patterns: The Mechanism of Burkholderia gladioli Pacifigorgiadiene Synthase

Chemistry – A European Journal, EarlyView.
The mechanism of pacifigorgiadiene synthase from Burkholderia gladioli was investigated through isotopic labeling experiments and DFT calculations. The results revealed an unexpected labeling pattern which appeared to be different in the main and the side products, requiring unprecedented mechanistic explanations, including a “break‐flip‐cyclise ...

Asymmetric Reduction of Unactivated Alkenes

Chemistry – A European Journal, EarlyView.
Unactivated alkenes rank among the most inert functional groups in synthesis and their selective reduction remains challenging. This Review charts the evolution from classical metal‐catalyzed hydrogenation to radical hydrogen atom transfer (HAT) and emerging biocatalytic concepts, highlighting how complementary mechanistic strategies, including the ...

Planar Chirality Controls Diastereotopicity in [2.2]Paracyclophanyl Cyclopropenes

Chemistry – A European Journal, EarlyView.
In this work, we report the synthesis of [2.2]paracyclophane‐substituted cyclopropenes via rhodium‐catalyzed cyclopropenation using a pCp‐derived carbene precursor. The planar chiral framework induces diastereotopic differentiation of otherwise equivalent alkyl substituents, which is reflected in their 1H NMR spectra.

Unlocking Heterobimetallic Architectures in a Symmetric PNNP Ligand Environment

Chemistry – A European Journal, EarlyView.
A symmetric PNNP ligand enables the modular assembly of heterobimetallic ZnRu and CoRu complexes from a mononuclear Ru(II) precursor. Ligand deprotonation triggers dearomatization and contraction of the metal–metal distance. Combined DFT and QTAIM analyses reveal metallophilic interaction in CoRu but not in ZnRu, highlighting controllable geometric and

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

Chemistry – A European Journal, EarlyView.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere
