Relative metal-hydrogen, -oxygen, -nitrogen, and -carbon bond strengths for organoruthenium and organoplatinum compounds; equilibrium studies of Cp*(PMe3)2RuX and (DPPE)MePtX systems

摘要: A series of ruthenium, Cp*(PMe/sub 3/)/sub 2/RuX (Cp* = eta/sup 5/-C/sub 5/Me/sub 5/), and platinum, (DPPE)MePtX (DPPE Ph/sub 2/PCH/sub 2/CH/sub 2/PPh/sub 2/), compounds have been prepared. The equilibria L/sub n/M-X + H-Y in equilibrium n/M-Y H-X (L/sub n/M (DPPE)MePt or 2/Ru; X, Y hydride, alkoxide, hydroxide, amide, alkyl, alkynyl, hydrosulfide, cyanide) examined. lower limit the Ru-N bond strength has estimated by analysis kinetics thermal decomposition 2/RuNPh/sub 2/. constants allow for determination relative M-X, M-Y dissociation energies (BDEs) each compounds. linear correlation to BDEs is found two dissimilar metal centers. generality other systems predictive value this are discussed.
