7789-68-6 Usage
Chemical Properties
Orange low melting lumps and powder
Uses
Titanium(IV) bromide is used as a Lewis acid catalyst in organic synthesis. It reacts with tetrahydrofurnan and 2-methylpyridine and forms adducts such as TiBr4(THF)2 and TiBr4(2-MePy). It is also used for the formation of titanium silicide thin films on silicon substrates.
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.

A Spectroscopic study of phenylboron halides

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.
