Beschreibung

Allgemeine Beschreibung

Titanium(IV) chloride participates in the Baylis-Hillman reaction of arylaldehydes with methyl vinyl ketone.[1] Neutral solutions of TiCl₄ having a pH in the range of 2.5 to 6.0 (prepared by the addition of magnesium oxide as a base) are used to synthesize nanosized titanium dioxide.[2]

Anwendung

Activates pyrrolidines for improved conversion, via a modified Bouveault reaction, to the corresponding α,α-dimethylamines.[3]

Promotes a highly selective aldol reaction of (S)-2-benzyloxy-3-pentanone in THF or DME.[4]

Titanium(IV) chloride has been used in the synthesis of anatase TiO₂ structures with macropores (250nm in diameter) and mesoscale pores (50nm in diameter).[5]
