Studies on Some Azomethine Derivatives of Titanium(IV)

Abstract
Synthesis and characterization of some new titanium(IV) complexes of Schiff bases have been described. These have been obtained by the reactions of titanium isopropoxide with dibasic tridentate Schiff bases derived by the condensation of 2,4-pentanedione, o-hydroxyacetophenone, salicylaldehyde and 2-hydroxy-1-naphthaldehyde with 3-hydroxy-1-propyl and 1-hydroxy-2-butylamines in 1:1 and 1:2 stcichiometry in the medium of anhydrous benzene. The isopropoxy groups of the diisopropoxy titanium Schiff base derivatives have been found to undergo replacement reactions with 2-methylpentane-2,4-diol and the resulting complexes are hydrolytically stable. Suitable structures based on IR, UV, PMR and mass spectral studies have been indicated for these new derivatives.
