Research topics:


Ø   Synthesis, structure and reactivity of organometallic and metal complexes – precursors for olefin transformations
(polymerization, metathesis, Heck and Suzuki coupling, cyclization, etc.) leading to “fine chemicals”
and „chemical specialities”.

Ø   Synthesis of metal complexes and organometallic compounds–precursors for electronic and magnetic materials
as well as biomaterials.

Ø   New catalysts for biodegradable and environment friendly polymers.

Ø   Chemical models of the active site of nitrogenase and manganese–calcium clusters relevant to photosynthetic
dioxygen-evolving centers.

Ø   Synthesis of organic and organometallic polyynes with potential use as nanoscale electronic devices.



Special equipment:


Ø   HI-TECH SF-51 stopped-flow spectrophotometer.
