On the Use of Iron in Organic Chemistry
Molecules, 2020 Transition metal catalysis in modern organic synthesis has largely focused on noble transition metals like palladium, platinum and ruthenium. The toxicity and low abundance of these metals, however, has led to a rising focus on the development of the ...

Bioactive glass-ceramic scaffolds from novel 'inorganic gel casting' and sinter-crystallization [PDF]
, 2017 Highly porous wollastonite-diopside glass-ceramics have been successfully obtained by a new gel-casting technique. The gelation of an aqueous slurry of glass powders was not achieved according to the polymerization of an organic monomer, but as the ...

Photochemical C-H Activation Enables Nickel-Catalyzed Olefin Dicarbofunctionalization.
Journal of the American Chemical Society, 2021 Alkenes, ethers, and alcohols account for a significant percentage of bulk reagents available to the chemistry community. The petrochemical, pharmaceutical, and agrochemical industries each consume gigagrams of these materials as fuels and solvents each ...

Chemodivergent manganese-catalyzed C–H activation: modular synthesis of fluorogenic probes
Nature Communications, 2021 Bioorthogonal diversification of peptides is generally dependent on impractical prefunctionalization methods. Here, the authors develop a manganese(I)-catalyzed C–H fluorescent labeling with BODIPY probes, which enables the development of activatable ...

The Influence of Galactic Cosmic Rays on Ion-Neutral Hydrocarbon Chemistry in the Upper Atmospheres of Free-Floating Exoplanets [PDF]
, 1989 Cosmic rays may be linked to the formation of volatiles necessary for prebiotic chemistry. We explore the effect of cosmic rays in a hydrogen-dominated atmosphere, as a proof-of-concept that ion-neutral chemistry may be important for modelling hydrogen ...
