Shedding light on comet Chury’s unexpected chemical complexity

The secret was hidden in the dust

07-Jul-2022

A team of researchers led by the University of Bern has for the first time identified an unexpected richness of complex organic molecules at a comet. This was achieved thanks to the analysis of data collected during ESA’s Rosetta mission at comet 67P/Churyumov-Gerasimenko, also known as Chury. ...

"Hand in hand in hand": three catalysts solve chemical problem

Research team develops new strategy to create molecular compounds without multi-step syntheses

14-Jan-2022

For organic synthesis, i.e. for the production of carbon-based compounds, it is important to develop synthesis processes by which the desired product can be obtained in good yield. At the same time, the processes should be sustainable: for example, they should use environmentally friendly and ...

Long-standing problem in organic chemistry solved

Chemists develop a bioinspired strategy for the controlled synthesis of polyenes

20-Jul-2020

They occur in nature, are reactive and play a role in many biological processes: polyenes. It is no wonder that chemists have for a long time been interested in efficiently constructing these compounds – not least in order to be able to use them for future biomedical applications. However, such ...

Catalyst adds fluorine-containing groups to make new compounds

25-Jan-2017

Drugs that contain one or more fluorine atoms tend to be more stable, more powerful, and easier for the body to absorb. For those reasons, drug developers would like to be able to incorporate fluorine or a fluorine-containing unit known as trifluoromethyl into new experimental drugs, but this has ...

E-selective macrocyclic ring-closing metathesis

11-Jan-2017

Using ring-closing metathesis to exploit the properties of carbon-carbon double bonds, researchers from Boston College and the Massachusetts Institute of Technology have developed a new catalytic approach for the preparation of compounds essential to drug discovery. The catalyst, which contains ...
