application

Titanium(IV) bromide (Titanium tetrabromide or TiBr4) can be employed as a Lewis acid catalyst in the synthesis of:
  • α-bromomethylene aldols by reacting with arylaldehydes and but-3-yn-2-one via Baylis-Hillman reaction.[1]
  • Titanium(II) bromide which along with copper forms an efficient catalytic system for Pinacol reaction.[2]
  • α-bromo-γ-hydroxyenamides by the reaction of ynamides and aldehyde or ketones.[3]

Features and Benefits

Used for the formation of titanium silicide thin films on Si substrates.
