Arene(phosphane)metal Complexes, II. Synthesis and Reactivity of the Metal Bases ArM(PR3)2 and ArM(PMe3)L (M = Ru, Os)

The ruthenium(0) and osmium(0) complexes ArM(PR3)2 (2 - 7, 11, 12) and ArM(PMe3)L (8 - 10, 13) are prepared by the reduction of PF6 and PF6, resp., with NaC10H8 at -78 deg C in THF.The thermally labile and very air-sensitive compounds 2 - 13 react with NH4PF6 or NH4PF6/CF3CO2H to form the stable hydridometall complexes PF6 (14 - 21) and PF6 (22 - 25).On reaction of 2 - 13 with CH3I and subsequent addition of NH4PF6 the compounds PF6 (27 - 34) and PF6 (35 - 38) are obtained.In general, themetal basicity of ArM(PR3)2 increases from ruthenium to osmium and for C6H6Ru(PR3)2 in the order PPh3 a mixture of two products, PF6 (40) and PF6 (41), which can be separated by further reaction of 40 with PF6 to form (PF6)2 (42).

BASIC METALS. XXIII. SYNTHESIS AND REACTIVITY OF LEWIS-BASE OSMIUM(0) COMPLEXES

The complexes C6H6OsL2 (L= PPh3, P(OMe)3) and C6H6OsLL' (L=PMe3, L'=C2H4 and C3H6) have been prepared by reduction of + and + with NaC10H8 in THF.These novel osmium(0) complexes are strong Lewis bases and react with NH4PF6 or MeI to form stable cation containing Os-H and Os-CH3 bonds; the reactions of the latter complexes are briefly discussed.
