Tetrabutylammonium iodide Chemical Properties,Uses,Production
Description
Tetrabutylammonium iodide is a organic ammonium compound, for which all four valences of a nitrogen atom are bonded organically. It is often used as phase-transfer catalysts and ion pair reagents.
Chemical Properties
Tetrabutylammonium iodide is an organic ammonium compound with the molecular formula C16H36IN. white or tan powder. Soluble in water and ethanol, slightly soluble in chloroform and benzene. Stable under normal temperature and pressure.
Uses
Tetrabutylammonium iodide is used in the preparation of novel quaternary amines to serve as antibacterial agents in the rise of drug-resistant bacteria,it is also used in phosphonium reversible inhibitors of cholinesterases.
Application
Tetrabutylammonium iodide may be used as a mobile phase additive in ion-pair high-performance liquid chromatography (IP-HPLC) assay of 4-aminopyridine in serum. It may also be used as a mobile phase additive in the analysis of tetracycline by reversed-phase IPC. The addition of tetrabutylammonium iodide regulates the retention of tetracyclines.
Tetrabutylammonium iodide can be used:
As an additive in the synthesis of fused triazole derivatives using palladium catalyst.
To prepare allyl-PEG-allyl, which is a key intermediate polymer used to synthesize fluorinated amphiphilic copolymers.
As a catalyst used in the synthesis of ethers.
Reactions
Tetrabutylammonium iodide (TBAI) has been used as a catalyst in the following reactions:
Synthesis of O-benzyl-N-Boc-L-tyrosine benzyl ester from N-Boc-L-tyrosine.
Conversion of 8-fluoro-1-aminonaphthalene into 1-(8-fluoro-naphthalen-1-yl)piperazine hydrochloride.
Synthesis of 1-(2,4-dichlorophenyl)-5-(4-(4-iodobut-1-ynyl)phenyl)-4-methyl-N-(piperidin-1-yl)-1H-pyrazole-3-carboxamide from 4-(4-(1-(2,4-dichlorophenyl)-4-methyl-3-(piperidin-1-ylcarbamoyl)-1H-pyrazol-5-yl)phenyl)but-3-yn-1-yl methanesulfonate.
Other reactions where TBAI can be used as a catalyst:
TBAI-tert-butyl hydroperoxide system can catalyze the conversion of α-methyl styrene derivatives into allylic sulfones by reacting with sulfonylhydrazides under metal-free conditions.
Palladium(0)-catalyzed cross-coupling between benzylic zinc bromides and aryl or alkenyl triflates.
Three-component coupling of amines, carbon dioxide, and halides to form carbamates in the presence of cesium carbonate.
General Description
Tetrabutylammonium iodide is a quaternary ammonium salt used in phase-transfer reactions. It is also used in regioselective ether cleavage reactions and as a source of iodide for nucleophilic displacement reactions.
Flammability and Explosibility
Not classified
Purification Methods
Crystallise the iodide from toluene/pet ether (see entry for the corresponding bromide), acetone, ethyl acetate, EtOH/diethyl ether, nitromethane, aqueous EtOH or water. Dry it at room temperature under a vacuum. It has also been dissolved in MeOH/acetone (1:3, 10mL/g), filtered and allowed to stand at room temperature to evaporate to ca half its original volume. Distilled water (1mL/g) is then added, and the precipitate is filtered off and dried. It can also be dissolved in acetone, precipitated by adding ether and dried in a vacuum at 90o for 2 days. It has also been recrystallised from CH2Cl2/pet ether or hexane, or anhydrous methanol and stored in a vacuum desiccator over H2SO4. [Chau & Espenson J Am Chem Soc 108 1962 1986, Beilstein 4 IV 558.]
