Copper-oxygen adduct complexes

25.06.2008
The new copper-oxygen adduct complexes according to the present invention are thermally stable at room temperature (and above), for the first time, as well as in oxygen-containing atmosphere, i.e. stable as a solid and suitable for being used as oxidation catalysts especially in industrial chemistry, for instance for the oxidation of benzene to phenol or of methane to methanol, for the oxidation of hydrogen, aromatic and aliphatic, saturated and unsaturated hydrocarbons as well as alcohols and amines.<p>

The possibility of using monovalent copper complexes with tripodal tetradentate ligands as an oxidising agent is definitely known by the state of the art. These are, however, thermally instable due to their oxygen sensitivity (i.e. they can only be conserved for a short time at temperatures significantly inferior to 0°C) and, thus, only usable in a restricted manner as oxidation catalysts. The invention at hand overcomes this disadvantage in the state of the art first by complexing a tripodal tetradentate ligand with a Cu-(I) compound and then by replacing the anion of this complex with a tetraarylborate and finally by exposing the [Cu-L]-tetraarylborate complex to a oxygen-containing atmosphere. This last reaction step is also suitable for being used in detecting oxygen.<p> These oxidation methods can be transferred by the invention at hand from laboratory scale to a industrial application: The copper-(II)-oxygen adduct complexes according to the present invention are, for instance, suitable for being deposited as reactive components in mesoporous phases such as molecular sieves or on zeolites or polystyrenes.

Im Focus: ScanCut project completed: laser cutting enables more intricate plug connector designs

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

Plug connectors are tiny and, at first glance, unremarkable – yet modern vehicles would be unable to function without them. Several thousand plug connectors...

Im Focus: New Strategy Against Osteoporosis

An international research team has found a new approach that may be able to reduce bone loss in osteoporosis and maintain bone health.

Osteoporosis is the most common age-related bone disease which affects hundreds of millions of individuals worldwide. It is estimated that one in three women...

Im Focus: AI & single-cell genomics

New software predicts cell fate

Traditional single-cell sequencing methods help to reveal insights about cellular differences and functions - but they do this with static snapshots only...

Im Focus: TU Graz Researchers synthesize nanoparticles tailored for special applications

“Core-shell” clusters pave the way for new efficient nanomaterials that make catalysts, magnetic and laser sensors or measuring devices for detecting electromagnetic radiation more efficient.

Whether in innovative high-tech materials, more powerful computer chips, pharmaceuticals or in the field of renewable energies, nanoparticles – smallest...

Im Focus: Tailored light inspired by nature

An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.

Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
