Titanium and zirconium 2-((p-tolylamino/p-tolylimino)methyl)phenolate (TAMP and TIMP) were prepared by reaction of Ti- and Zr-alcoholates with 2-((p-tolylamino)methyl)phenol (TAMPH) and 2-((p-tolylimino)methyl)phenol (TIMPH) in alcohol. To characterize these compounds, 1 H, 13 C NMR, FTIR, mass spectroscopies, and elemental analysis were used. The TAMP and TIMP metal compounds can be formulated as (TAMP) 3 M 2 (OR)O 2 and (TIMP) 4 M 2 O 2 , respectively. The catalytic activity of these compounds was checked in polymerization reactions with propylene oxide (PO) and e-caprolactone (e-CL) and Ti-TAMP was effective . Poly-propylene oxide (PPO) and poly-caprolactone (PCL) were identified by 1 H, 13 C NMR and gel permeation chromatography (GPC).
