The reduction of trans-RuCl2(PMe3)4 with Na/Hg and of trans-OsCl2(PMe3)4 with sodium in the presence of catalytic amounts of naphthalene gives the complexes RuH(η2-CH2PMe2)(PMe3)3 (III) and OsH(η2-CH2PMe2PMe2), (IV) in good yields. An equilibrium with the metal(0) isomers [M(PMe3)4] cannot be detected by NMR spectroscopy. III and IV react with dihalomethanes CH2X2 (X = Cl, Br, I) and CH3I to form mixtures
