A series of ruthenium, Cp*(PMe3)2RuX (Cp*=ν5-C5Me5), and platinum, (DPPE)MePtX (DPPE=Ph2PCH2CH2PPh2), compounds have been prepared.The equilibria LnM-X + H-Y = LnM-Y + H-X (LnM=(DPPE)MePt or Cp*(PMe3)2Ru; X, Y=hydride, alkoxide, hydroxide, amide, alkyl, alkynyl, hydrosulfide, cyanide) have been examined.A lower limit of the Ru-N bond strength has been estimated by analysis of the kinetics of the thermal decomposition of Cp*(PMe3)2RuNPh2.The equilibrium constants allow for the determination of relative M-X, M-Y bond dissociation energies (BDEs) for each series of compounds.A linear correlation of LnM-X to H-X BDEs is found for the two dissimilar metal centers.The generality to other systems and predictive value of this correlation are discussed.
