General description

Titanium(IV) chloride participates in the Baylis-Hillman reaction of arylaldehydes with methyl vinyl ketone. 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.

Application

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

The Ti(IV)-catalyzed Ugi condensation of α-amino acids with electron-rich aromatic aldehydes performs adequately even with sterically demanding α-amino carboxylate salts. The reaction occurs diastereoselectively, in some cases with virtually complete diastereoselectivity. A stereochemical rationale for the reaction is proposed.

Pyrrolopyrrole aza-BODIPY analogues were synthesized from diketopyrrolopyrrole and heteroaromatic amines in the presence of titanium tetrachloride. These novel compounds exhibit intense absorption in the visible region and strong emission with high fluorescence quantum yields greater than 0.8.
