First Row Transition Metals in Olefin Metathesis: The Role of Iron and Manganese

ChemCatChem, EarlyView.
Olefin metathesis is primarily a love story with molybdenum and ruthenium, but the dream is to transition to first‐row transition metals, such as manganese and especially iron. Will this be feasible? This work discusses some challenges associated with this migration.

A Reexamination of CO2 Reduction with Fe2S2 Hydrogenase Mimics: Lessons in Using a Hydrogen Evolution Reaction Catalyst for CO2 to Formate Catalysis

ChemElectroChem, EarlyView.
Combining cyclic voltammetry, infrared spectroelectrochemistry, and density functional theory methods, the reduction of CO2 by an [FeFe] hydrogenase mimic was examined. Despite its ability to form stable reduced hydride species, this catalyst does not selectively reduce CO2 to HCOO− under the tested conditions.

Electrooxidation of Anhydrous Glycerol: Kinetics and Selectivity

ChemElectroChem, EarlyView.
This work investigates glycerol electrooxidation in anhydrous conditions to narrow down the range of possible products. Preferential oxidation of glycerol to glyceraldehyde was achieved via homogeneous but not heterogeneous catalytic pathways. Further improvements in the redox mediator and catalyst design are needed to improve the performance.As a by ...

Ni‐Based Catalysts for 5‐Hydroxymethylfurfural Electrooxidation Coupled with Hydrogen Production

ChemElectroChem, EarlyView.
The co‐electrolysis of H2O and 5‐hydroxymethylfurfural (HMF) using Ni‐based catalysts, under alkaline conditions, co‐produces low‐carbon hydrogen and furandicarboxylic acid. This review delves into the electrooxidation mechanism of HMF electrooxidation, presents recent advancements in the performance of Ni‐based catalysts and highlights the effects of ...

Mono‐Ethyl‐Phosphonates: Functional Group Masking Strategy to Stabilize and Optimize the Pharmacokinetics of Rare Earth Radiochelates

ChemistryEurope, EarlyView.
Prodrug strategies are used to enhance the pharmacokinetics of small molecule drugs. Here, this approach to rare earth coordination complexes is adopted with applications as diagnostic and therapeutic radiopharmaceuticals: a mono‐ethyl‐phosphonate polyazamacrocyclic chelator for 44Sc and 177Lu reduces blood and bone uptake.
