What is Titanium tetraisopropanolate?
Chemical properties
colourless to light yellow liquid
The Uses of Titanium tetraisopropanolate
Catalyst especially for asymmetric induction in organic syntheses; in preparation of nanosized TiO2. Complexing agent in sol-gel process.
The Uses of Titanium tetraisopropanolate
To a solution of 10% AcOH in MeOH was added the SM (1 equiv) and dry acetone (5 equiv). The solution was stirred at RT 1 h, after which time it was cooled to 0 C and treated with NaCNBH3 (1.5 equiv). The reaction was stirred at RT for 5 h. The mixture was concentrated and the residue brought to pH = 10 using Na2CO3. The mixture was extracted with EtOAc and the org layer was washed with H2O, brine, dried (Na2SO4), and concentrated to dryness. The crude material was purified by silica gel column chromatography (2% MeOH/DCM) to provide the pdt as a yellow solid.
The Uses of Titanium tetraisopropanolate
Titanium(IV) isopropoxide is used as a precursor for the preparation of titanium and barium-strontium-titanate thin films. It is useful to make porous titanosilicates and potential ion-exchange materials for cleanup of radioactive wastes. It is an active component of Sharpless epoxidation as well as involved in the synthesis of chiral epoxides. In Kulinkovich reaction, it is involved as a catalyst in the preparation of cyclopropanes.

Definition
ChEBI: Titanium(IV) isopropoxide is a titanium coordination entity consisting of a titanium(IV) cation with four propan-2-olate anions as counterions.
General Description
Tetraisopropyl titanate appears as a water-white to pale-yellow liquid with an odor like isopropyl alcohol. About the same density as water. Vapors heavier than air.
Air & Water Reactions
Highly flammable. Fumes in air. Soluble in water. Decomposes rapidly in water to form flammable isopropyl alcohol.
Reactivity Profile
Metal alkyls, such as TETRAISOPROPYL TITANATE, are reducing agents and react rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Thus, they are likely to ignite on contact with alcohols.
Health Hazard
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Flammability and Explosibility
Flammable
Purification Methods
Dissolve it in dry *C6H6 , filter if a solid separates, evaporate and fractionate. It is hydrolysed by H2O to give solid Ti2O(iso-OPr)2 m ca 48o. [Bradley et al. J Chem Soc 2027, 1952, Bradley et al. J Chem Soc 469 1957, Beilstein 1 II 328, 1 IV 1469S.]
