Titanium (IV) Bromide Powder Applications
Titanium (IV) bromide powder 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.
- Titanium(II) bromide which along with copper forms an efficient catalytic system for Pinacol reaction.
- α-bromo-γ-hydroxyenamides by the reaction of ynamides and aldehyde or ketones.
