BOCHUM, GERMANY: A team from the Ruhr-University Bochum (RUB) Chair of Inorganic Chemistry II has developed new chemical compounds that make catalysts more efficient. The properties of a catalyst are not only determined by its catalytically active centre but also by atoms or molecules bound to it, which are called ligands.

In the journal Angewandte Chemie, researchers led by Prof Dr Viktoria Daschlein-Gessner described a new class of what are known as phosphine ligands. With their electronic and spatial properties, they ensure that catalysts are more active and more stable.

Patent pending

The Bochum-based chemists showed that high yields at low temperatures would be possible in gold-catalysed reactions with the ligands – and without it being necessary to laboriously optimise the reaction. The team assumes that the results can be transferred to other catalysts and that the already patent-pending systems are worth considering for broader industrial application.

Easy to produce

The novel ligand systems can be synthesised in numerous ways from commercially available precursors. “It is thus easy to produce them in different versions and customise their properties to suit a certain application,” explained Daschlein-Gessner, a member of the cluster of excellence Ruhr Explores Solvation.
