The synthesis of a heterodinuclear cryptate;

Synthesis and characterization of some transition metal cryptates;

Dinuclear silver(I) cryptate (ClO_4)_2 was synthesized by template condensation of 3,5-dimethyloxylphenyl-1,3-dialdehyde with tri(3-aminopropyl)amine in the presence of silver ion,and the dinuclear copper(I) cryptate (ClO_4)_2was synthesized by transmetallation reaction of the dinuclear silver(I) cryptate with Cu(CH_3CN)_4ClO_4.

To study the structure and characterization of transition metal chelate complexes, we synthesized in this paper a new complex by the condensation of tren and tri(o benzenmethyl ethyl ether)amine, and prepared a series of corresponding transition metal chelate complexes of tren and tri(o benzenmethyl ethyl ether)amine complex by replacement reaction.

Based on the cryptand H3L drived from the condensation of tris(2-aminoethyl) amine(tren) with 2,6-diformy-4 -methoxy phenol(dmp)[1],a new yttrium cryptate was synthesized and characterized by several methods.

Polymerization of methyl methacrylate by titanium complex bearing bis(phenoxy-imine) chelate ligands;

Treatment of this ligand with NaH and TiCl4·2THF in THF respectively,a new titanium complex 1 was obtained of which the structure was characterized by 1H NMR and elemental analyses.

Polymerization of butyl methacrylate by titanium complex having two phenoxy-imine chelate ligands;
