Scope

Our research interests include the chemistry of transition metal complexes with P-donor ligands and the chemistry of elements of main groups, with particular emphasis on phosphorus and boron chemistry. The main goal of our research is to develop new inorganic synthesis methods and the aim of the projects is to discover new types of reactivity and catalysts useful in important chemical processes.

Current projects focus mainly on the following issues:

  • Low-valent phosphorus compounds: the project provides fundamental information about low-valent phosphorus compounds that exhibit high reactivity. Like carbene complexes of transition metals, their phosphinidene and phosphido counterparts can have applications in organic synthesis and chemical catalysis.
  • Synthesis and research on the reactivity of polyphosphorus compounds: the project aims to develop new, polydentate P-donor ligands and coordination polymers with application with synthesis of new materials and catalysis.
  • Reactivity of Lewis frustrated hydrogen pairs (FLP): these studies develop new, non-metallic hydrogenation catalysts.
  • Activation of small inorganic molecules (CO2, CS2, SO2, N2O, catalyzed by phosphorus and boron compounds): these studies open the way to completely new reactions using simple substrates.

At the disposal of the members of the research group there are the following apparatus:

  • X-ray diffractometer
  • NMR spectrometer
  • glove box
  • 6 work stations in an inert gas atmosphere equipped with vacuum lines

Cooperation offer

We invite students of all levels and specialties as well as other research groups. For students, we offer interesting topics for diploma theses, the opportunity to participate in research projects and work in a young, dynamically developing team.
