Synthetic Studies and Structural Aspects of some Metallacyclic Derivatives of Titanium (IV) - Better Precursors for Titania

Abstract

Titanium(IV) complexes of the type [(acac)2Ti(O-G-O] and [(acac)2Ti(OCH2CH2SH)2] {where G = (CH2)2, CH2CH(CH3), CH2CH(C2H5), CH(CH3)CH(CH3) have been synthesized in high yield by the interaction of the precursor [(acac)2Ti( OR)2] {where R = Pri , Et} with a variety of glycols and thioglycols in 1:1 and 1:2 molar ratios in refluxing benzene under anhydrous condition yield heteroleptic derivatives. On the basis of physico-chemical analyses, a cis-octahedral environment around Ti (IV) is proposed.
