Abstract

Structural models for Li intermediates during metallations of two different organic precursors having -NH-C=O units are isolated and structurally characterised, and shown to be complexed mono- and di-meric azaenolates with (-N=C-OLi·xB)_n (B = Lewis base) groupings; contrary to earlier assumptions, the structures imply that the N-(rather than the O-) centres of these species would direct second lithiations to nearby C-H bonds although it has proved impossible thus far to detect the proposed dilithiated systems.
