    • Several molecular structures of 1,1-dilithioalkanes with oxygen, nitrogen, or aromatic substituents have been reported. These aggregates are formed by the strong interaction of Li with the substituents, rather than interactions between Li and the central carbon atoms of neighboring molecules. For a review see: C. Strohmann, D. Schildbach, in The Chemistry of Organolithium Compounds (Eds.: Z. Rappoport, I. Marek), Wiley, Chichester, 2004, pp. 941-996.
