Unequal partners : Reactions of complexes of the form [Cp*M(μ‐H) 4 M′Cp*] ( 1 : M=M′=Ru; 2 : M=Ru, M′=Os; 3 : M= M′=Os) with P(OMe) 3 provide evidence of kinetic and thermodynamic heterometallic effects. Heterometallic complex 2 induces selective addition of P(OMe) 3 to the Ru center in an accelerated reaction. Moreover, the incorporated P(OMe) 3 migrates unidirectionally from Ru to Os owing to the formation of a strong OsP bond.
