Regio‐ and Diastereoselective C–C Silylation of Cyclopropyl Acetates Harnessing Fluorinated Poly(pyridyl)Borate Rhodium Catalysts

open access: yesChemistry – A European Journal, EarlyView.
Fluorinated poly(pyridyl)borates have been utilized to stabilize rhodium‐diene complexes and as supporting ligands in rhodium‐catalyzed redox‐neutral C–C silylation of cyclopropyl acetates, producing silicon‐containing heterocyclic products, dioxasilolanes.

SmI2/Sm‐Induced Reductive Silacyclization of Alkene/Diene Derivatives Using Dichlorosilanes or 1,2‐Dichlorodisilanes via Reductive Radical‐Polar Crossover

open access: yesChemistry – A European Journal, EarlyView.
A SmI2/Sm‐mediated silacyclization unlocks a concise route to 4–7‐membered silacycles from simple unsaturated substrates and dichlorosilanes/disilanes. The complementary functions of samarium reductants trigger a reductive radical–polar crossover, offering a versatile strategy for constructing multiple Si─C bonds efficiently.

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...

Recent Developments in the Field of Air‐Stable Nickel(0) Precatalysts for Cross‐Coupling Reactions

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The development of bench‐stable Ni(0) sources aims to replace air‐sensitive [Ni(COD)2] (cod = cycloocta‐1,5‐diene) with easy‐to‐handle alternatives. Through a targeted ligand design, using electron‐deficient dienes, carbenes, and fluorophosphines, researchers have achieved air‐ and moisture‐tolerant complexes that show high catalytic activity in cross ...

Dinuclear Rhodium(I)–N‐Heterocyclic Carbene Complexes as Alkyne Hydropyridonation Catalysts

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Catalyst Improvement by NHC tuning: A series of new RhI–NHC dinuclear complexes has been revealed as efficient alkyne hydropyridonation catalysts. 333053IMes complex displays the highest reactivity of the series, suggesting that a moderate steric demand combined with balanced σ‐donation facilitates precatalyst activation and substrate exchange.
