cis-cis- 1,3,5-triaminocyclohexane (30.0 nig, 0.232 mmol) was added to an ampoule charged with dichlorotris(triphenylphosphane)ruthenium(II) (196 mg, 0.204 mmol) dissolved in dichloromethane (20 mL), causing an instant colour change from black to orange. The solution was stirred at 50C for 4 days in the sealed vessel, during whichtime the solution changed colour to yellow and a white precipitate formed. The precipitate was removed by filtration and the filtrate reduced in volume to approx. 1 mL in vacuo. The product was precipitated by addition of pentane (20 mL) as an orange powder, and washed twice with pentane (20 mL). Yield: 115 mg (86.8 %, 0.177 mmol of RuCl2(K3-c -tach)(PPh3).CH2Cl2).

Example B2: Preparation of [(CI)2Ru(Pphenyl3)(ligand L2)], K2tolueneyl 272.5 mg (0.284 mmol) of dichlorotris(triphenylphosphine)ruthenium(ll) and 160.0 mg (0.296 mmol) of ligand L2 are placed in a 10 ml Schlenk tube and admixed with 6.5 ml of dry toluene under argon. The dark suspension is stirred overnight at room temperature, resulting in a colour change to orange-red. After addition of 4 ml of dry pentane, the stirrer is switched off and the supernatant orange solution is filtered off with suction from the orange solid. The solid is washed five times with 4 ml each time of pentane and dried in a high vacuum. This gives 244 mg (88% of theory) of the title compound as an orange powder. 31P-NMR (C6D6, 121.5 MHz, ppm): 49.7 (d, J = 40), 61.2 (d, J = 40).

General procedure: The same basic method, as described here for [RuCl(PPh3)2(LMe,H)]Cl, was followed for all the complexes in this study. Asuspension of [RuCl2(PPh3)3] (0.36 g, 0.4 mmol) and LMe,H (0.15 g,0.4 mmol) in dry dichloromethane (15 cm3) was stirred for 3 h atroom temperature. This yielded an orange precipitate, which wascollected by filtration. Alternatively, the products 3-6 were solublein the reaction mixture, and were precipitated from it by careful addition of diethyl ether. In either case, the resultant solids werewashed repeatedly with diethyl ether to remove excess PPh3, thendried in vacuo.
