An Active Form of Titanium III Chloride

Submitted by ANN R. HERMES and GREGORY S. GIROLAMI Checked by RICHARD A. ANDERSEN  

The reduction of TiCl4 with hexamethyldisilane does not afford titanium(II) chloride as reported by Narula and Sharma.1 Instead, the method affords an active form of titanium(III) chloride that is useful for the preparation of other titanium(III) species. 

The reactivity studies show that the reduction of TiCl4 with Me3SiSiMe3 gives a form of TiCl3 that is more reactive than the purple form of TiCl3 available commercially.
