Chiral, bridged bis(imidazolin-2-ylidene) complexes of palladium

Varieties of chiral, bridged bisimidazolium salts as well as the synthesis of palladium complexes of general formula [bridge{NC(H)C(H)N(R∗)C¯}2PdBr2] with the corresponding chelating N-heterocyclic carbene ligands is reported. This is the first systematic study of chiral bis(imidazolin-2-ylidene)palladium(II) complexes bearing chiral groups on the endocyclic nitrogens. Structural proof of such a chiral palladium(II) complex is presented by way of an X-ray diffraction study of complex 3a.

A systematic study of chiral bis(imidazolin-2-ylidene)palladium(II) complexes is presented, bearing the chiral group on the ring nitrogens. A structural proof of the chiral palladium(II) complexes is represented by a X-ray diffraction study.Figure optionsDownload as PowerPoint slide
