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.


Moisture sensitive. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents and strong acids. It reacts with water to produce titanium dioxide.

Catalyst for transesterification, avoiding acidic or basic conditions. The reaction is carried out such that one alcohol is removed to displace the equilibrium: Synthesis, 138 (1982); Org. Synth. Coll., 8, 201 (1993). For application to carbamates, including Boc to Cbz conversion, see: J. Org. Chem., 62, 7096 (1997).

Epoxy alcohols can also be obtained in high yield in one pot by hydroperoxidation of alkenes with singlet oxygen in the presence of Ti(O-i-Pr)4: J. Am. Chem. Soc., 111, 203 (1989).

Also catalyzes the ring-opening of 2,3-epoxy alcohols (e.g. from the above reactions) with various nucleophiles, including amines, thiols, thiolate anions, halides, carboxylates etc. The mild conditions result in increased regioselectivity: J. Org. Chem., 50, 1557 (1985).
