Tetrabutylammonium tribromide Chemical Properties,Usage,Production
Chemical Properties
Insoluble in H2O; soluble in anhydrous acetic acid (50 g/100 mL), MeCN (300 g/100 mL), CHCl3, trichloroethylene (10 g/100 mL), THF, dioxane; very soluble in DMF, DMSO; slightly soluble in alcohols; soluble in acetone with slow reaction, giving lachrymatory solution. Avoid washing reaction vessels with acetone prior to using this reagent. It should be handled in a fume hood. Anhydrous, orange nonhygroscopic stable solid; purity more than 98%; stable bromine degree (1 g = 2.07 mequiv Br2). Red crystals when recrystallized from DMF solution.
Uses
Tetrabutylammonium Tribromide is used in the synthesis of antimicrobial agents via chalcones. Also used in the synthesis of potent tubulin polymerization inhibitors.
Uses
- Tetrabutylammonium tribromide (TBATB) is a salt of the lipophilic tetrabutylammonium cation and the linear tribromide anion. It is used as a phase transfer catalyst in organic synthesis as well as a mild brominating agent. A wide range of O-isopropylidene derivatives can be prepared from the sugars and their derivatives on reaction with acetone at room temperature by employing 2 mol % of tetrabutylammonium tribromide as a catalyst. Good yields, low catalyst loading, mild reaction conditions, and a non-aqueous workup procedure are some major advantages of this protocol.
- Tetrabutylammonium tribromide as an efficient generator of HBr for an efficient chemoselective reagent for acetalization of carbonyl compounds.
- It is sometimes used as a reagent used in organic synthesis as a conveniently weighable, solid source of bromine.
- Tetra-n-butylammonium tribromide is useful for the preparation of vicinal dibromides from alkenes and alkynes and alfa-bromo acetals.
- it is utilized to generate hydrogen bromide, which is used as an efficient chemoselective reagent for acetalization of carbonyl compounds.
Synthesis
1643-19-2
38932-80-8
General procedure for the synthesis of tetrabutylammonium tribromide from tetrabutylammonium bromide: A sample of molybdic acid monohydrate (H2MoO4) was taken. H2O (0.16 mmol, 0.029 g) in a 250 mL glass beaker and 30% hydrogen peroxide (H2O2, 15.52 mmol, 1.76 mL) was added to it. The mixture was stirred at room temperature for 30 min. The slightly cloudy solution was filtered through Whatman No. 1 filter paper on a glass funnel. The clarified filtrate was collected in a 250 mL glass beaker and kept in an ice water bath. Tetrabutylammonium bromide (TBAB, 15.51 mmol, 5 g) and potassium bromide (KBr, 31.01 mmol, 3.69 g) dissolved in 0.3 M H2SO4 (15.52 mmol, 51.77 mL) were slowly added to the solution under continuous stirring, resulting in the formation of a yellow precipitate. The mixture was continued to be stirred in an ice-water bath for 1 h and then left to stand in an ice-water bath for 2 h to give an orange-yellow compound of tetrabutylammonium tribromide (TBATB). The compound was separated by filtration using Whatman No.1 filter paper under suction. It was dried in melted CaCl2 and recrystallized from acetonitrile. The yield was 7.23 g (96.7%), melting point: 76-77°C. The chemical analysis, IR and conductance of the compound were in good agreement with the data reported in the literature. Analytical data: compound correctly analyzed C16H36NBr3: Calculated values C, 39.86; H, 7.52; N, 2.90; Br, 49.71%. Measured values C, 39.41; H, 8.28; N, 2.78; Br, 49.53%.
