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
