Abstract

The butyl and isopropyl derivatives (4I, 5Br) of chiral pool derived bis-imidazolium dehydrohexitol salts have been prepared. The ditopic N-heterocyclic carbenes 4 and 5 form dinuclear Ag(I) and Pt(II) complexes. All compounds were fully characterised by multinuclear NMR spectroscopy. The bis-imidazolium salt 4I and platinum complexes cis-[Pt-2(mu-2)(dmso)(2)Cl-4] and cis-[Pt-2(mu-4)(dmso)(2)Cl-4] were characterised by X-ray crystallography. In the case of the Pt(II) complexes, the carbene ring is positioned in a sterically preferred orientation, approximately perpendicular to the platinum coordination plane. The H-1, C-13, N-15 and Pt-195 NMR spectra of the platinum complexes show the presence of rotamers due to hindered rotation about the carbene-metal bond.
