From palladium(II) or platinum(II) bis(isonitrile) complexes and from gold(I) isonitrile complexes, both easily available from simple precursors, the corresponding mono-N-heterocyclic carbene (NHC) complexes could be obtained selectively in good yields under very mild conditions. The reagents are simple b-chloroammonium salts in the presence of a weak base. Unsymmetric NHC complexes are accessible. Thus over only two steps from simple metal precursors a broad variety of NHC complexes is available, the method is ideal to quickly assemble catalyst libraries. The palladium complexes are active pre-catalysts in Suzuki cross-coupling even with the additional isonitrile ligand on palladium.

Using the new modular and convergent approach to isocyanide-N-hetrocyclic carbene-platinum(II) complexes, eight new compounds have been synthesised. For three of these, detailed structural data could be obtained by X-ray crystal structure analyses. This new family of organoplatinum complexes is catalytically active for hydrosilylation reactions; styrene and phenylacetylene could be used as substrates; triethylsilane and 1,1,1,3,5,5,5-heptamethyltrisiloxane could be used as reagents. With some of the new platinum pre-catalysts, excellent regioselectivities of up to 98 : 2 could be obtained, and turnover numbers up to 840 were achieved.

(S)-6-(4-(Methoxycarbonyl)phenyl)-1,1'-bis-2-naphthol, ac hiral 1,1'-bis-2-naphthol (BINOL) derivative, wasp repared via SuzukiC ÀCc oupling and immobilized onto diamine-functionalized multiwalled carbonn anotubes. The BINOL was first derivatized with ac arboxylic acid, capable of forming an amide linkage with the amine-carbon nanotube modified surface. The 4-methoxyphenylboronic acid was replaced by 3-fluoro-4-(methoxycarbonyl)phenylboronic acid and (S)-6-(3-fluoro-4-(methoxycarbonyl)phenyl)-1,1'-bis-2-naphthol was obtained and used as ap robe to better quantify the organic material. It was found that in the hybrid material, 1/3 of amine groups have been transformed into the corresponding amide (S)-BINOL derivative. The chemical and electronic integrity of the chiral BINOL ligand is maintained after the ligand immobilization. Evaluation in diethyl zinc and Ti(OiPr) 4 -catalyzed alkylation of benzaldehyde showed that both methoxycarbonylphenyl andf luoromethoxycarbonylphenyl BINOL moieties do not significantly influence the catalytic activity or selectivity of the process. However,w hen hybridm aterials were used, similar activities were obtained, but with lower enantioselectivities.T his result could be due to ac ompetitive alkylation reactiono ccurring on the carbon surfaceo rb yt he constraint caused by the ligand proximity on the support surface.
