Delineation of the Critical Parameters of Salt Catalysts in the N-Formylation of Amines with CO2

Paul Joseph Dyson, Daniel Ortiz Trujillo, Martin Hulla, Dmitry Vasilyev

N-formylation of amines with CO2 is base-catalyzed and studies of salt catalysts reveal that the reaction is efficiently catalyzed by "free" floating anions of high basicity, as represented in the cover image. More information can be found in the Full Pape ...

Synthesis of Organic Super-Electron-Donors by Reaction of Nitrous Oxide with N-Heterocyclic Olefins

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Andrzej Sienkiewicz, Basile Curchod, Léonard Yannick Maurice Eymann, Ophélie Marie Planes, Paul Varava, Yizhu Liu, Andrei Shved

The reaction of nitrous oxide (N2O) with N-heterocyclic olefins (NHOs) results in cleavage of the N–O bond and formation of azo-bridged NHO dimers. The latter represent very electron-rich compounds with a low ionization energy. Cyclic voltammetry studies s ...

A Cobalt-Iron Double-Atom Catalyst for the Oxygen Evolution Reaction

Xile Hu, Duncan Thomas Lindsay Alexander, Lichen Bai

Single-atom catalysts exhibit well-defined active sites and potentially maximum atomic efficiency. However, they are unsuitable for reactions that benefit from bimetallic promotion such as the oxygen evolution reaction (OER) in an alkaline medium. Here we ...

Stability profiles of transition metal oxides in the oxygen evolution reaction in alkaline medium

Xile Hu, Aliki Moysiadou

The electrochemical water splitting reaction can convert renewable electricity into clean hydrogen fuel. The efficiency of water splitting is limited to a large extent by the sluggish oxygen evolution reaction (OER). Numerous transition metal oxides have b ...

Catalyst design for the transformation of CO2 into value-added products

Felix Daniel Bobbink

The mass-utilization of fossil resources has led to a dramatic increase in carbon dioxide (CO2) production, most of which is released directly into the Earth's atmosphere, resulting in global warming. Efforts to contain CO2 emissions and to capture, store ...

Mechanistic Study of the N-Formylation of Amines with Carbon Dioxide and Hydrosilanes

Paul Joseph Dyson, Gabor Laurenczy, Martin Hulla

N-formylation of amines with CO2 and hydrosilane reducing agents proceeds via fast and complex chemical equilibria, which hinder easy analysis of the reaction pathways. In situ reaction monitoring and kinetic studies reveal that three proposed pathways, vi ...
