Abstract

The present work describes the synthesis and characterization of a series of complexes of formula LAlR(AlR₂)₂(R = Et, L = Salean (1), Salpan (2), Salophan (3), Salomphan (4); R = ⁱBu, L = Salean (5), Salpan (6), Salophan (7), Salomphan (8)). The use of the comparatively bulky ⁱBu group in 5 results in a complex which adopts a cis ligand configuration as shown by an X-ray structural analysis. The trimetallic complexes display ¹H NMR spectra that are consistent with a rigid solution-state geometry. The presence of a deshielding interaction between the protons on the alkyl group 13 reagent and the arylamine backbones of the Salophan and Salomphan ligands will be discussed. Additionally, the crystal structures of SalophanGaMe(GaMe₂)₂ (9) and SalomphanGaMe(GaMe₂)₂ (10) are reported.
