摘要：

Two trianionic amine triphenolate ligands are introduced and their isopropoxide Ti(IV) complexes synthesized. The two complexes are mononuclear and C-3-symmetrical on the NMR timescale. High barriers to inversion (DeltaG double dagger > 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. (C) 2001 Elsevier Science B.V. All rights reserved.
