This contribution surveys recent progress in the thermochemistry of lanthanide, actinide, and early transition element organometallic compounds. General trends in metal-ligand bond enthalpy patterns across the transition series can be understood largely on the basis of straightforward electronegativity concepts. Metal-ligand bonding energetics in such unusual species as metallacycles, early transition element carbonyls and benzynes, as well as in actinide carbonyls are also quantified. Such data furthermore provide a deeper insight into d0, f0- centered β-hydride/β-alkyl elimination, cyclometalation, and hydrocarbon functionalization processes, as well as into U(IV)-centered elimination reactions. New reactions which are examined in the light of metal-ligand bond enthalpy data include binuclear organolanthanide-centered hydrocarbon activation and organo- lanthanide-catalyzed hydroamination of olefins.
