Rapid mobilization of noncrystalline U(IV) coupled with FeS oxidation

Rizlan Bernier-Latmani, Malgorzata Alicja Stylo

The reactivity of disordered, noncrystalline U(IV) species remains poorly characterized despite their prevalence in biostimulated sediments. Because of the lack of crystalline structure, noncrystalline U(IV) may be susceptible to oxidative mobilization und ...

Direct carbon dioxide hydrogenation to formic acid in acidic media

Paul Joseph Dyson, Gabor Laurenczy, Séverine Joëlle Moret

The present invention relates to a method of producing formic acid in a catalysed chemical reaction from hydrogen gas and carbon dioxide gas, said reaction being conducted in an acidic medium comprising a polar solvent over a wide range of temperatures at ...

Synthesis of cyclic carbonates from diols and CO2 catalyzed by carbenes

Paul Joseph Dyson, Felix Daniel Bobbink, Martin Hulla, Shoubhik Das, Weronika Gruszka

The synthesis of cyclic carbonates from epoxides and CO2 is a well-established reaction, whereas the synthesis of cyclic carbonates from diols and CO2 is considerably more challenging, and few efficient catalysts are available. Here, we describe heterocycl ...

Nickel-catalyzed Hydrosilylation of Alkenes and Transition-Metal-Free Intermolecular α-C-H Amination of Ethers

Ivan Buslov

Transition-metal-catalyzed hydrosilylation of olefins is one of the most important methods for the preparation of organosilicon compounds, which have broad applications in both synthetic and material chemistry. For decades, precious metals, principally pla ...

Transition Metal-Free Intermolecular alpha-C-H Amination of Ethers at Room Temperature

Xile Hu, Ivan Buslov

We describe a new method for the intermolecular amination of the alpha-C-H bonds of ethers. A hypervalent iodine reagent was used as oxidant to enable the amination of cyclic and acyclic alkyl ethers with a wide range of amides, imides, and amines. The ami ...

Reactions of Grignard Reagents with Nitrous Oxide

Rosario Scopelliti, Kay Severin, Euro Solari, Alexander Tskhovrebov

The chemical activation of nitrous oxide (N2O) can be achieved by organocalcium, organosodium, and organolithium compounds. Grignard reagents, on the other hand, are believed to be inert. We demonstrate that this generalization is not correct. Some aliphat ...

Organic molecules as mediators and catalysts for photocatalytic and electrocatalytic CO2 reduction

Xile Hu, Yeonji Oh

Reduction of CO2 by electrochemical and photoelectrochemical methods to produce carbon-rich fuels is a heavily pursued research theme. Most of the current efforts are focused on the development of transition-metal-based catalysts. In this tutorial review, ...

Effects of carbonate on the electrolytic removal of ammonia and urea from urine with thermally prepared IrO2 electrodes

Christos Comninellis, Agnieszka Kapalka, Véronique Amstutz, Kai Udert

Recent studies have shown that electrolysis can be an efficient process for nitrogen removal from urine. These studies have been conducted with urea solutions or fresh urine, but urine collected in NoMix toilets and urinals has a substantially different co ...

Di-n-butyltin(IV)-catalyzed dimethyl carbonate synthesis from carbon dioxide and methanol: An in situ high pressure 119Sn{1H} NMR spectroscopic study

Gabor Laurenczy

The reactivity of five di-n-butyltin(IV) complexes, n-Bu2Sn(OR)(2) (1), n-Bu2SnO (3), n-Bu2Sn(OR)O (4), (n-Bu2SnO)(2)(CO2) (6) and (n-Bu2SnO)(6)(n-Bu2SnOR)(2)(CO3) (7) (R = CH3), with CO2, suggested as possible catalyst precursors and key-interme ...
