Homogeneous Catalysis with Organometallic Compounds

Our group performs fundamental research in the areas

  • coordination properties of metals and ligands
  • metal complexes with small molecules (ethyne, H2, etc)
  • structural dynamics of complexes
  • reaction mechanisms and
  • organometallic mesogenes (plastic crystals).

Transition metals under focus are Ni, Pd, and Pt, which often are used in combination with main group metals compounds (Li, Mg, Al, Ge, Sn), and Co–Ir.

Organometallic Plastic Crystals

While plastic crystals (dynamically-orientationally disordered mesogens) are so far rare in organometallic chemistry, we discovered that formally five-coordinate ionic Ni(II) complexes [(π-allyl)NiL3]Y and neutral M(I) complexes (π-allyl)ML3 (M = Co, Rh, Ir) with L = PMe3, P(OMe)3, and other ligands undergo a phase transition from the ordered to a plastic phase. The plastic properties arise from mobility of the π-allyl group in the solid-state. For the ionic Ni compounds, besides motion of the anions Y, the cations appear to tumble on their site in the lattice, whereas the neutral M(I) complexes rotate about an axis. For recrystallization, some compounds require partial ordering in a glassy-crystalline state.

Cisplatin-related Metal Complexes

Among the most prominent anti-cancer drugs are cisplatin, carboplatin, and oxaliplatin. Therapy with these drugs is frequently associated with a bunch of serious side-effects, and inherent or acquired platinum resistance is also an obstacle. In the search for complexes which may overcome these problems we are studying Pt complexes of the parent bispidine (3,7-diazabicyclo[3.3.1]nonane, C7H14N2) (e.g., (C7H14N2)PtCl2 x 3 H2O) and its derivatives.

Novel Complexes of the Late Transition Metals (Ni, Pd, Pt)

Our group has a long history in studying complexes of Ni, Pd, Pt, and Cu with acyclic and cyclic alkene and alkyne ligands, in particular those comprising the functional groups in 1,6- or 1,6,11-sequence. At present, in cooperation with a Spanish group (A. Roglans, University of Girona) the coordination of macrocyclic mixed polyene-yne ligands at Ni(0) is studied.
