Abstract
Two different methodologies were used to attempt the synthesis of a novel P‐N ligand,
denoted as PACNAC for the similarity to the analogous NACNAC and ACAC ligands.
Although the synthesis of PACNAC was not successful, each methodology led to interesting
discoveries. First, a number of lithium complexes of ketoimines were isolated and studied by Xray
crystallography and NMR spectroscopy revealing some interesting substituent based effects
on the structure, solubility and solution state behaviour. The X‐ray data of the two known and
two related novel ketoimines were also collected and compared to the lithium complexes.
Secondly, the synthesis of novel alkynyl imines along with the new alkynyl diimines by novel
synthetic routes and studied by x‐ray crystallography, NMR, electrochemistry, and UV‐Visible
spectra.
