The research focuses on the synthesis and characterization of yttrium complexes with a bulky arylamido ancillary ligand. The main reactants used in the experiments include anhydrous YCl3, arylamido lithium 2,6-iPr2C6H3NSiiPr3Li, LiCH2SiMe3, and THF as a solvent. The synthesis involved the reaction of YCl3 with arylamido lithium to form an anionic mono-arylamido-ligated yttrium dichloride complex (1), which was then alkylated with LiCH2SiMe3 to produce an anionic arylamido-ligated yttrium tris(alkyl) complex (2). The complexes were characterized using NMR spectroscopy, elementary analysis, and X-ray structural determination, which confirmed their structures and provided insights into their steric and electronic properties. The study aimed to understand the reactivity of rare earth metal complexes and explore the potential of arylamido ligands in modifying these properties.
