New way to produce important molecular entity

Chemists develop method for simple production of vicinal diamines

13-Dec-2022

Among the most common structures relevant to the function of biologically active molecules, natural products and drugs are so-called vicinal diamines - in particular, unsymmetrically constructed diamines. Vicinal diamines contain two functional atomic groups responsible for the substance ...

Researchers solve a problem in organic chemistry

Breakthrough in “meta-C-H functionalization” of pyridines

21-Nov-2022

In chemicals used in agriculture, as well as in pharmaceuticals and a variety of materials, pyridines are often found as so-called functional units which decisively determine the chemical properties of substances. Pyridines belong to the group of ring-shaped carbon-hydrogen (C-H) compounds ...

Researchers show that chiral oxide catalysts align electron spin

Researchers from Münster and Pittsburgh look for causes of spin polarisation in these materials

23-Sep-2022

Controlling the spin of electrons opens up future scenarios for applications in spin-based electronics (spintronics), for example in data processing. It also presents new opportunities for controlling the selectivity and efficiency of chemical reactions. Researchers recently presented first ...

New method correlates atomic force microscopy with the function of single-atom catalysts

Researchers study catalytic activity of copper atoms

09-Sep-2022

Fuel cells convert chemical reaction energy into electric power and heat. They are used, for example for the development of electric vehicles, in aviation and aeronautics or for sustainable energy supplies. During the conversion of energy, the catalytic reduction of oxygen plays an important ...

On the way to cell-type materials

Physicists decode the dynamic interaction between molecular machines in metal-organic frameworks

05-Jul-2022

Molecular machines control a sizeable number of fundamental processes in nature. Embedded in a cellular environment, these processes play a central role in the intracellular and intercellular transportation of molecules, as well as in muscle contraction in humans and animals. In order for the ...

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 ...

More Data in Chemistry

Clearer reporting of negative experimental results would improve reaction planning in chemistry

13-Jun-2022

Databases containing huge amounts of experimental data are available to researchers across a wide variety of chemical disciplines. However, a team of researchers have discovered that the available data is unsuccessful in predicting the yields of new syntheses using artificial intelligence (AI) ...

Breakthrough in synthesis chemistry: Chemists use light energy to produce small molecular rings

New synthesis route for producing sensitive molecules under mild reaction conditions

30-May-2022

In the search for new active agents in medicine, molecules whose atoms are linked in rings are becoming increasingly important. Such ring systems have particularly suitable properties for producing such active agents and they are driving the development of innovative treatments for malignant ...

Chemists discover new reactivity of strained molecules

Light energy enables the reaction of double bonds with strained single bonds to produce three-dimensional molecules

24-Mar-2022

In synthetic organic chemistry, so-called cycloadditions are a particularly important class of reactions. With this type of reaction, ring-shaped molecules can be constructed simply and efficiently by joining (“adding“) two compounds that each contain double bonds. A team led by Prof. Dr. Frank ...
