Defining Reactivity Differences in Sterically Crowded (η5-C5Me5)3M Complexes Based on Metal Size and Lanthanide vs Actinide Effects

Reactions between (η5-C5Me5)3M and (η5-C5Me5)2M′(μ-Ph)2BPh2 (M, M′ = La, Ce, Pr, Nd, Sm, and U; M radius < M′ radius) were examined to evaluate the relative steric crowding in the (C5Me5)3M series ...
