1. Multidentate N-heterocyclic carbene ligands
N-Heterocyclic carbenes feature the beneficial property of a combined strong σ-donor- and weak π-acceptor character. We want to make use of this in the design of transition metal catalysts.
1.2 Catalytic properties of the Rh-pincer complexes
Reaction of the Rh(I)-pincer-complex with allyl halides proceeds fast and leads to formation of complexes with exclusively η1-coordinated allyl ligands. These complexes were tested as catalysts in the allylic alkylation.2

Due to their unique planar geometry, the dipyrido carbenes offer interesting properties. As we could show by means of their (CO)5Cr- and (CO)5W complexes they show a similiar net-donor character as saturated or unsaturated NHCs.5
The complex Rh(COD)(dipy)(PPh3)OTf turned out to be a good catalyst in the hydrosilylation of dialkyl- and diaryl ketones as well as α,β-unsaturated ketones.6
