Organolithium compounds dynamics

Three promised chapters on the dynamic behaviour of organolithium compounds, on chiral alkyllithium amides in asymmetric synthesis and on the intramolecular carbolithia-tion reaction were not delivered. Although some material related to the first of these two chapters appear partially in other chapters, we hope that the missing chapters will appear in a future volume. 

Chemically induced dynamic nuclear polarization (CIDNP) was first reported in 1967 in independent work from three different laboratories. The effects of free radicals on NMR spectra were revealed (Fig. 6) in studies of radicals from peroxides (equation 62) and azo compounds, as well as radicals generated from the reaction of alkyl halides and organolithium compounds. ... 

We have shown how organolithium compounds adopt a variety of structures which differ in state of aggregation and degree of solvation. These species interconvert rapidly at equilibrium by different mechanisms, such as intermolecular C—Li exchange ligand transfer and dissociation-recombination processes as well as first-order reorganizations such as inversion and rotation. Dynamics of many of these processes have been determined by our methods of NMR line shape analysis.
