General description
Atomic number of base material: 22 Titanium
Application
Titanium tetrachloride may be used in the vapor synthesis of titania powder by oxidaition. It may be used as a catalyst in cross and asymmetric aldol reactions. Other possible uses of titanium tetrachloride is in the synthesis of :
- γ,δ-unsaturated alcohols from allylsilanes and carbonyl compounds,
- N-Phosphinoylimines and N-sulphonylimines from aromatic aldehydes,
- Homoallyl ethers from allylsilanes and acetals.6
