- Reactivity of dinuclear arene ruthenium complexes: Reactions of the hydrido complex [(p-Me-C6H4-Pri)2Ru 2Cl2(μ-Cl)(μ-H)] with NaX and HX (X=F, Cl, Br, I)
-
The dinuclear hydrido complex [(p-Me-C6H4-Pri)2Ru 2Cl2(μ-Cl)(μ-H)] (1) reacts with the sodium halides NaX in methanol to give the halogen analogues [(p-Me-C6H4-Pri)2Ru 2X2(μ-X)(μ-H)] (2: X=F, 3: X=Br, 4: X=I). With HX, complex 1 reacts to give the tetrahalo complexes [(p-Me-C6H4-Pri)2Ru 2X2(μ-X)2] (5: X=Cl, 6: X=Br, 7: X=I); in the case of X=I, a large excess of HI leads to the formation of the cationic complex [(p-Me-C6H4-Pri)2Ru 2(μ-I)3]+ (8). The X-ray structure analysis of 1 shows a dinuclear Ru2 backbone with two terminal chloro ligands being trans with respect to each other as the two p-cymene ligands, the two bridging ligands lie in a plane perpendicular to the plane defined by the terminal chloro ligands and the ruthenium atoms.

- A simple method of regenerating areneruthenium dichloride dimers, 6-arene)>2, from their monomeric adducts with amines or tertiary phosphines, RuCl2(η6-arene)L
-
The monomeric amine or tertiary phosphine complexes RuCl2(η6-arene)L (arene=benzene, p-cymen) can be reconverted into their dimeric precursors 6-arene)>2 by heating with 1,5-cyclooctadiene (COD), 2-propanol, and anhydrous Na2CO3 and subsequent treatment of the resulting ruthenium(0) complexes Ru(η6-arene)(η4-COD) with HCl; the ligand L can be recovered.
