7789-68-6 Usage
Uses
Used in Organic Synthesis:
Titanium(IV) Bromide is used as a Lewis acid catalyst in organic synthesis, facilitating various chemical reactions and improving their efficiency. It reacts with tetrahydrofuran (THF) and 2-methylpyridine, forming adducts such as TiBr4(THF)2 and TiBr4(2-MePy), which are crucial in the synthesis of complex organic molecules.
Used in Semiconductor Industry:
In the semiconductor industry, Titanium(IV) Bromide is utilized for the formation of titanium silicide thin films on silicon substrates. These thin films are essential in the manufacturing of integrated circuits and other microelectronic devices, as they provide improved electrical conductivity and enhanced device performance.
Purification Methods
Purify it by distillation. The distillate forms light orange hygroscopic crystals. Store it in the dark under N2 preferably in sealed brown glass ampules. [Olsen & Ryan J Am Chem Soc 54 2215 1932.]
Check Digit Verification of cas no
The CAS Registry Mumber 7789-68-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7789-68:
(6*7)+(5*7)+(4*8)+(3*9)+(2*6)+(1*8)=156
156 % 10 = 6
So 7789-68-6 is a valid CAS Registry Number.

Preparation and proposed structure for bis[bis(dimethylamino)bromoborane]-tris(titanium tetrabromide)
Suliman,Schram
, p. 920 - 922 (2008/10/08)
Treatment of [(CH3)2N]2BBr with TiBr4 affords {[(CH3)2N]2BBr}2{TiBr 4}3. The stoichiometry of the latter was established by determination of the reactant ratio and by nucleophilic degradation affording TiBr4·N(CH3)3 and [(CH3)2N]2BBr. A structure is proposed for {[(CH3)2N]2BBr}2{TiBr 4}3 based on infrared assignments and the unusual stoichiometry of this compound.
A Spectroscopic study of phenylboron halides

, p. 9 - 17 (2008/10/08)
Phenylfluoroboranes have been prepared by the fluorination ofthe corresponding bromides with titanium tetrafluoride. The infrared spectra of the phenylhaloboranes, R3-nBXn (RC6H5, XF, Cl, Br, I), have been recorded in the 4000-4250 cm-1 region; an assignment of the fundamentals is suggested and characteristic frequency trends are discussed. An evaluation of the spectral data suggests that the structure of phenylfluoroboranes is distinctly different from that of the other halides in the series.
