Abstract
Abstract Novel sandwich-type ruthenium complexes [Ru(η6-arene)(p-cymene)](BF4)2, in which the η6-arene ligands have long alkyl chains, were prepared. These complexes were dispersed in water to form corresponding micelles. Alkoxy moieties on the η6-arene ligands were reacted with OH− to afford the corresponding phenolic species. Thus, [Ru(p-undecyloxyanisole)(p-cymene)]2+ was converted to [Ru(η6-p-methoxyphenolate)(p-cymene)]+ through the unexpected demethylation by treatment with Na2CO3 with the micelle remaining. The micelle collapsed when similar ruthenium complex bearing dodecyl 2-(4-methoxyphenoxy)acetate as an arene ligand was treated with Na2CO3 aq.
