Chemists develop reaction cascade to produce fluorinated molecules

"Molecular origami" creates new structures in a single operation

14-Jul-2023 - Fluorine is found rarely in naturally occurring organic molecules. However, this chemical element is indispensable for the production of pharmaceuticals or agrochemicals. Synthetic chemistry has an important role to play in the development of new fluorine-containing molecular fragments. Simple, ...

Scientists streamline a widely used chemical reaction, creating new manufacturing opportunities

This research should have a far-reaching impact: it allows scientists to forge valuable carbon-carbon bonds used in the pharmaceutical and agrochemical industries, and beyond

11-May-2023 - A team of scientists from the University of Ottawa has developed an innovative technique to manufacture complex chemical structures from easily accessible substrates, making it one of the simplest and most practical methods for converting alcohols into their arylated equivalents. This innovative ...

A radical new approach in synthetic chemistry

Pulse radiolysis experiments help reveal how unpaired electrons at one end of a molecule can initiate chemistry at 'distant' locations

28-Nov-2022 - Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory helped measure how unpaired electrons in atoms at one end of a molecule can drive chemical reactivity on the molecule’s opposite side. As described in apaperrecently published in theJournal of the American ...

Chemists to capture atmospheric methane with sugar

Can a carbohydrate actually suck methane, a greenhouse gas, directly out of the air?

22-Nov-2022 - Researchers at the University of Copenhagen’s Faculty of Science are in the process of finding out. Methane gas is 86 times more potent than CO2 and one of the major contributors to global warming. It is estimated that methane accounts for 30 percent of all global warming from gaseous emissions. ...

Chemists develop new multi-component reaction

More environmentally friendly approach produces complex molecular structures in one step: Ketyl radicals "tamed" by photocatalysis

15-Jun-2022 - A more sustainable use of chemical resources is part of the United Nations' Agenda 2030. Synthetic chemists are therefore working to design and carry out efficient syntheses. Within the synthetic organic chemist's arsenal, processes that link several molecules (coupling partners) in a single step ...

The AETX files: Work to unravel widespread bald eagle fatalities gathers pace

Scientists succeed in totally synthesizing eagle killer venom

15-Jul-2021 - This March, the discovery of the toxic natural substance aetocthonotoxin (AETX) attracted huge media attention. In a study published in Science, pharmacists from Halle University proved the role of this substance in triggering mass species extinctions among American bald eagles and other birds of ...

Chemists look to the future of materials design

19-May-2020 - Scientists at the University of South Carolina and Columbia University have developed a faster way to design and make gas-filtering membranes that could cut greenhouse gas emissions and reduce pollution. Their new method, published in Science Advances, mixes machine learning with synthetic ...

Largest Synthetic Polysaccharide Assembled

Linear 100-mer polysaccharide within 188 hours

05-May-2020 - Chemists at the Max Planck Institute of Colloids and Interfaces (Potsdam, Germany) have set a milestone by preparing the two largest carbohydrates ever assembled. Using an Automated Glycan Assembly (AGA) instrument originally developed at the institute they prepared a linear 100-mer and achieved ...

Artificial enzymes convert solar energy into hydrogen gas

08-Oct-2018 - In a new scientific article, researchers at Uppsala University describe how, using a completely new method, they have synthesised an artificial enzyme that functions in the metabolism of living cells. These enzymes can utilize the cell's own energy, and thereby enable hydrogen gas to be produced ...
