Abstract

Two trianionic amine triphenolate ligands are introduced and their isopropoxide Ti(IV) complexes synthesized. The two complexes are mononuclear and C₃-symmetrical on the NMR timescale. High barriers to inversion (ΔG‡ > 65 KJ mol^-1) between the enantiomers of each complex were found. The complex derived from the bulkier tripodal ligand shows a better resistance to hydrolysis.
