The chiral diketiminate ligand bis-N,N’-(2-phenylethyl)-2,4-diiminopentane, 1H, was synthesized in good yields in a 1-step reaction from chiral amine and acetylacetone. Reaction of 1Li(THF) with N-bromosuccinimide yielded the succinimide-substituted ligand 2H. Cu complexes were obtained by reaction of the ligand with a basic Cu source in the presence of coordinating Lewis bases, and 1Cu(NCMe), 1Cu(DMAP), 1Cu(PPh3), 1Cu(2,6-xylyl isonitrile), 2Cu(PPh3), and 2Cu(2,6-xylyl isonitrile) were prepared and, for the most part, characterized by x-ray diffraction studies. Compared to their more common analogs with aromatic substituents on N, 1 and 2 seem to be more basic (1 > 2) and sterically more demanding (2 > 1). Their Cu complexes are less stable than those of aryl-substituted diketiminates and tend to decompose by disproportionation, most probably after dissociation of the coordinated Lewis base. Despite the rotational freedom around the N-R* bond, the complexes are sterically rigid, a necessary requirement for potential applications in enantioselective catalysis.
