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.
