Modular Rh‐Catalyzed Synthesis and Biological Profiling of Diverse Pentafluorobenzenesulfonamide Reactive Fragments

Chemistry – A European Journal, EarlyView.
A modular Rh‐catalyzed synthetic approach enabled the preparation of diverse reactive fragments from available substrates. The reactive fragments modified Aurora A kinase via several distinct modification reaction classes. In a complex biological environment, the constellation of modified proteins depended critically on the reactive fragment structure.

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

Chemistry – A European Journal, EarlyView.
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

Iridium Complexes of a Triazole‐Derived Pincer Ligand: Synthesis, Reactivity, and Transfer Dehydrogenation Catalysis

Chemistry – A European Journal, EarlyView.
Ir pincer complexes bearing a triazole architecture in the pincer backbone and O‐ancillary chelating ligands are presented. These were employed in the catalytic transfer dehydrogenation of alkanes as well as of saturated heterocycles. Reactivity of these complexes with silver salts and Lewis acids produced various cationic iridium complexes.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Low‐Temperature Initiation Enhances HCN and NH3 Formation From Methane and NO Over Pt/Al2O3

Chemistry – A European Journal, EarlyView.
Hydrogen cyanide (HCN) was formed from CH4 and NO over Pt/Al2O3 at low temperatures. Increasing NO concentration and optimizing reaction‐start conditions significantly enhanced HCN yield. In situ FTIR and DXAFS measurements revealed that dynamically balancing Pt‑CO and Pt‑CN surface species, particularly their desorption under temperature‑swing ...

Hydroprocessing of synthetic kerosene over a non‐sulphided Ni/Al2O3 catalyst: Impact of alcohols and ketones on alkene conversion

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.
