Abstract
Nuclear magnetic resonance (NMR) spectroscopy is the most widely used analytical technique
to study the structure and dynamics of organolithium compounds, which are the most
popular reagents in organic synthesis due to their great diversity and high reactivity.
The main strength of this method is that it allows direct analysis in solution of
the aggregation, dynamic, and solvation state of reactive intermediates. In this review,
we present the NMR tools (nD) involving the 6Li isotope and DOSY experiments with internal references and illustrate their contribution
in the structural and dynamic characterization of organolithium compounds in solution
through some selected example.
