Consecutive donor-base exchange in anthracenyllithium compounds

Abstract

Selective and consecutive donor-base addition and exchange in the same organolithium complex was monitored by structural determination, although it is feasible to fine-tune the composition of a mixed-base complex by stoichiometric addition of a second donor base. Remarkably, the length of the Li-C α bonds is proportional to the reactivity as measured by frontier orbital energies with increasing amounts of the better donor base.
