- Preparation and proposed structure for bis[bis(dimethylamino)bromoborane]-tris(titanium tetrabromide)
-
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
-
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.
