摘要: Abstract 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 studied by X-ray crystallography NMR spectroscopy. PGSE diffusion studies used to recognize (a) ion pairing as a function of solvent (b) larger molecular volumes. Several arene–Ru-complexes shown be useful catalyst precursors in the hydrolysis terminal aryl alkynes afford acetophenones.
