Reactions of [Ru(η6-C6Me6)Cl2]2 with 1,4-piperazinedicarbonitrile in 1:2 and 1:1 molar ratios in dichloromethane leads to the quantitative formation of [Ru(η6-C6M6)Cl2(ppz)] and [Cl2(η6-C6Me6)Ru-(-μ-ppz)- Ru(η6-C6Me6)Cl2] respectively. These complexes have been characterized by elemental analyses, infrared, electronic, 1H and 13C NMR spectroscopy. Ligand substitution reactions of these complexes with EPh3 (E = P, As and Sb) have also been studied.

Reaction of [{Ru (η6- C6Me6)Cl2}2] with 1,4-dicyano trans2-butene gives a binuclear complex[{Ru(η6 - C6Me6)Cl2}2 (μ -DCBT)] which undergoes metathetical reactions with EPh3 ( E = P, As, Sb) and NN donor bases, viz., 2,2′-bipyridine and l,10′-phenanthroline. The resulting products have been characterised by elemental analyses, IR, UV-Vis 1H and 13C NMR spectroscopy.

Reactions of [{Ru(η6-C6Me6)Cl2}2] with 4-cyanopyridine leads to the formation of neutral mono and dimeric complexes viz., [Ru(η6-C6Me6)Cl2(CNPy)] (1) and [Cl2(η6-C6Me 6)Ru-(μ-CNPy)-Ru(η6-C6Me 6)Cl2] (H). Complex (I) undergoes metathetical reactions with EPh3 (E = P, As & Sb) and N-donor heterocyclic bases yielding corresponding substitutional products which have been characterized by elemental analyses and spectroscopic (IR, UV/vis, 1H and 13C NMR) studies.

The η-hexamethylbenzenehydridoruthenium(II) complexes RuHCl(η-C6Me6)L (L = PPh3 (11), AsPh3 (12), P(C6H4-p-F)3 (14), P(C6H4-p-Me)3 (15), P(C6H4-p-OMe)3 (16), P-t-BuPh2 (17), P-i-PrPh2 (18), P-i-Pr3 (19), PCy3 (20) and P-t-BuMe2 (21)) have been made by heating 2, the ligand and sodium carbonate in propan-2-ol.The triarylphosphine complexes 11, 14 and 15 react with methyllithium to give aryl artho-metallated hydridoruthenium(II) complexes such as (22) and 19 similarly gives the isopropyl cyclometallated complex (29) as a mixture of diastereomers.Reaction of 17 with methyllithium gives initially the t-butyl cyclometallated complex (25) which isomerizes by a first order process (k ca. 0.2 h-1 in C6D6 or THF-d8 at 50 deg C) to the aryl ortho-metallated complex (26).The similarly generated isopropyl cyclometallated complex (27) has not been isolated in a pure state owing to rapid isomerization to (28); both 27 and 28 exist as a pair of diastereomers.The formation of the cyclometallated complexes and the isomerizations are thought to involve intermediate 16-electron ruthenium(0) complexes Ru(η-C6Me6)L.
