It is a pleasure for us to dedicate this paper to Professor Kees Vrieze, whose creativity, wisdom and charm have delighted us all over many years. P.S.P. thanks the Swiss National Science Foundation and the ETH Zurich, for financial support and A.A. thanks M.U.R.S.T. for a research grant (cofinanziananto 2000–2002). P.S.P. also thanks Dr. Mark Burk for the gift of the Me-Duphos bidentate ligand as well as Johnson Matthey for the loan of precious metal salts.

N2 - Cationic [RuCl(arene)(Me-Duphos)]Cl complexes, arene=η6-benzene and η6-p-cymene, Me-Duphos=1,2-bis-((2R,5R)-2,5-dimethylphospholano) benzene) have been prepared and studied by X-ray crystallography and NMR spectroscopy. PGSE NMR diffusion studies have been used to recognize (a) ion pairing as a function of solvent and (b) larger molecular volumes. Several arene-Ru-complexes have been shown to be useful catalyst precursors in the hydrolysis of terminal aryl alkynes to afford acetophenones.
