Inorg Chem. 2006 Aug 7;45(16):6490-6.Binding of a calixarene containing a single phosphorus ligand and three hydroxyl groups, calixPNMe2(OH)3, 1, toward titanium and zirconium is investigated to yield insight into the factors that determine the strength of the phosphorus/metal interaction within the constraint of the calixarene. Treatment of 1 with tetrakis(dimethylamino)titanium yields three complexes, 4a, 4b, and 4c, each of which shows the loss of 3 mol of dimethylamine in the reaction with the titanium bound to three oxygens.
