Özet

The reaction of [RuCl2(p-cymene)](2) with 1,3-dialkylimidazolinium salts 1a-f in the presence of a small excess of cesium carbonate yields chelated eta(6)-arene, eta(1)-carbene ruthenium complexes 2a-f. All synthesised compounds were characterized by elemental analysis, NMR spectroscopy. The catalytic activity of RuCl2(eta(6)-arene, eta(1)-imidazolinylidene) complexes 2a-f was evaluated in the direct arylation of 2-phenylpyridine with chlorobenzene derivatives. (C) 2009 Elsevier B.
