The reaction is irreversible and can be used to synthesize aliphatic and aromatic esters. In addition, there are no complications involving water removal or azeotrope formation. Boron tribromide can be used in place of boron trichloride, but the bromide has a stronger tendency to halogenate the alkyl group of the alcohol (26). Boron trifluoride does not give the ester, but gives either a complex or dehydrated product. [Pg.215]

A comparison of catalytic activity of the triphenyl phosphate complexes of boron trifluoride,boron trichloride and boron tribromide showed that comparable rates of polymerization were obtained using the chloride or bromide complexes. The fluoride complex gave about half the rate of the bromide or chloride comparable molecular weights were obtained in all three cases. [Pg.316]

Boron trichloride, boron tribromide, and boron triiodide, in contrast to the trifluoride, are all rapidly hydrolyzed in water (explosively so in the case of BI3) to generate B(OH)3 and HX as indicated above, all are stronger Lewis acids than BF3. While BC13 and BBr3 are volatile liquids, BI3 is an unstable white solid that polymerizes on standing. The BX anions are all known, but the larger ones —especially BI4—require stabilization by a large cation. [Pg.166]

Boron Tribromide and Boron Triiodide. Boron tribromide is prepared commercially in relatively small quantities by the bromination of boron carbide, and its commercial use is limited. No commercial use for boron triiodide has been reported. Laboratory quantities of boron tribromide can be prepared by the reaction of aluminum bromide with boron trifluoride or a metal fluoroborate. Boron triiodide can be prepared in small quantities by the reaction of boron or a metal tetrahydroborate with iodine. [Pg.439]

Boron is a Group HTA element that forms many covalent compounds by bonding to three other atoms. Typical examples include boron trifluoride, BF3 (mp — 127°C) boron trichloride, BCI3 (mp — 107°C) boron tribromide, BBr3 (mp -46°C) and boron triiodide, BI3 (mp 50°C). All are trigonal planar nonpolar molecules. [Pg.316]

Rearrangement. Tertiary A -benzylglycinamides are subject to [l,2]-rearrangement by consecutive treatment with BBr3 and Et3N to afford phenylalaninamide analogues. The transformation cannot be effected by replacing boron tribromide with boron trifluoride. [Pg.79]
