Beschreibung

Anwendung

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.
• 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.

Leistungsmerkmale und Vorteile

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