Introduction
Recent laboratory measurements have shown that the unique electronic configurations of lanthanide cations lead to unique trends in the kinetics of chemical bond activation by these cations across the periodic table. As early as 1988, Shilling and Beauchamp (1) proposed that electron promotion from the [4f.sup.n][6s.sub.1] ground state to the [4f.sup.n-1][5d.sub.1][6s.sub.1] excited state was required for these cations to be effective in C--H and C--C bond activation and insertion. A plethora of investigations into lanthanide ion chemistry followed, in part to further characterize this requirement, but also motivated by general interests in the ...
