Don prepared Cp*2Yb(bipy) sometime in his first-or second-year as a graduate student at Berkeley in 1978 or 1979, but the compound did not see the light of print until some 23 years later (Schultz, Boncella, Berg, Tilley, and Andersen, Organometallics, 2002, 21 , 460). A model for the electronic structure of its ground state as a multiconfigurational, closed-shell singlet, in which the ytterbium is intermediate valent, took 7 more years to unravel (J.Am.Chem.Soc., 2009, 131 , 6480 and 2010, 132 , 17537). This presentation will describe the evolution of the electronic structure by successive students working in room 547 Latimer Hall and how an understanding of the electronic ground state of the general class of ytterbocene adducts with heterocyclic-nitrogen bases leads to new reactivity patterns.
