This review is devoted to the investigation of reactions of ytterbocenes with diimines. These reactions are found to be strongly influenced by the steric crowding in the coordination sphere of the metal atom and the coordination capacities of π‐aromatic ligands coordinated to the ytterbium. The reactions may occur with oxidation of the ytterbium atom as well as with retention of its oxidation state. C–C bond formation, C–H bond activation, C=N bond insertion, and oxidative Yb–C bond cleavage processes are documented for reactions of ytterbocenes with diimines. Steric overcrowding of the coordination sphere of the ytterbium atom can induce “extra” reducing ability of ytterbocenes and allow them to act not only as one‐ but also as two‐electron reductants with respect to diimines.
