Ligand bond disruption

In homoleptic D-type systems such as Ln(p-diketonate)3, catalytic activity is directed by the formation of Lewis acid (catalyst) /base (substrate) pairs [182], Hence metal-ligand bond disruption and formation processes are pushed into the background. 

In more recent studies, Sonnenberger, Mbrss, and Marks [18] have determined metal-alkyl ligand bond disruption enthalpies (formally defined as in eq.(ll) for the gas phase process of eq.(12)) for a... 

Recent thermochemical studies by Bruno, Morss, and Marks [48] and Sonnenberger, Morss, and Marks [49] have determined thorium-ligand bond disruption enthalpies (D, eqs.(ll) and (12)) for a large series of Cp2ThR2 complexes. Data are set out in Table II and are portrayed schematically in Figure 6. Because these parameters are derived from heats of alcoholysis (eqs.(30),(31)), the dual entries in the Table...

Bruno et al. [50, 51] have carried out extensive thermochemical studies of actinide-ligand bond disruption enthalpies, D (equations (23.11) and (23.12)), for CpIjThRj and CP2UR2 complexes. Stepwise alcoholysis is observed for thorium ...
