General description

Titanium(IV) isopropoxide is a Lewis acid catalyst used in organic reactions like Sharpless epoxidation.

Application

Novel metal oxide/phosphonate hybrids were formed from titanium(IV) isopropoxide in a two-step sol-gel process. Starting material for barium-strontium-titanate thin films. Used to make porous titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes. Applied in the formation of a heterosupermolecule consisting of a TiO2 nanocrystallite-viologen electron acceptor complex whose light-induced electron transfer has been demonstrated.

Caution

may discolor on storage

Other Notes

Additive used in the Sharpless asymmetric epoxidation of allylic alcohols; Catalyst used for transesterifications with various alcohols under neutral conditions
