Titanium tetraisopropanolate reacts with water to deposit titanium dioxide:
Ti{OCH(CH3)2}4 + 2 H2O → TiO2 + 4 (CH3)2CHOH
This reaction is employed in the sol-gel synthesis of TiO2-based materials in the form of powders or thin films.
Typically water is added in excess to a solution of the alkoxide in an alcohol.
The composition, crystallinity and morphology of the inorganic product are determined by the presence of additives (e.g. acetic acid), the amount of water (hydrolysis ratio), and reaction conditions.
Titanium tetraisopropanolate is also used as a catalyst in the preparation of certain cyclopropanes in the Kulinkovich reaction.
Prochiral thioethers are oxidized enantioselectively using a catalyst derived from Ti(O-i-Pr)4.
