An efficient method to synthesize novel highly sterically hindered acenaphthene-based α-diimine ligands bearing bulky diarylmethyl moiety was achieved by two-step reactions. These reactions could be carried out on a scale of 100 g with no chromatography involved. On the basis of this method, a series of novel highly sterically hindered acenaphthene-based α-diimine Pd(II) and Ni(II) complexes, imidazolium precursors and the corresponding NHCs-metal complexes were also successfully synthesized. These novel complexes can offer great potential for metal-catalyzed polymerizations and organic reactions.

Six ferrous chloride complexes ((Ar-BIANX)FeCl2: Ar = 2,6-diisopropylphenyl (Dipp), X = F (1), Cl (2), Me (3); Ar = mesityl (Mes), X = F (4), Cl (5), Me (6)) supported by sterically bulky asymmetric bis(arylimino)acenaphthene (BIAN) ligands were prepared through the treatment of anhydrous FeCl2 with the corresponding ligands in a molar ratio of 1:1. The compounds were characterized by X-ray crystallography, IR, NMR and electrochemical methods. This series of complexes represents rare examples of structurally characterized iron compounds bearing asymmetric bidentate BIAN ligands. The complexes were tested for catalytic hydrosilylation of aldehydes and ketones at room temperature, and moderate to good yields of alcohol derivatives were obtained after hydrolysis workup.
