Applications

Phase transfer catalyst Tetra-n-butylammonium hydrogen sulfate shows antibacterial properties due to the presence of the quaternary amine and the counter ion. It serves as a phase-transfer catalyst, surface-active agent, solvent, intermediate, active ingredient for conditioners, antistatic agent, detergent sanitizers, softener for textiles and paper products, emulsifying agents and pigment dispersers. It is used as an efficient catalyst in the N-alkylation reactions of benzanilides, cyclization of beta-amino acids to beta-lactams, conversion of nitriles to amides, dehydrohalogenation of aryl 2-haloethyl ethers to give vinyl ethers and in the oxidation of alcohols.

Notes

Moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.

Références bibliographiques

Widely used phase-transfer catalyst; see Appendix 2. Some illustrative applications are given below:

Benzanilides have been N-alkylated in the presence of NaOH and K2CO3: Synth. Commun., 18, 2011 (1988).

It was the most effective catalyst studied for the cyclization of ß-amino acids to ß-lactams by methanesulfonyl chloride and KHCO3: Chem. Lett., 443 (1981).

In the dehydrohalogenation of aryl 2-haloethyl ethers to give vinyl ethers, this catalyst was found much more effective than the corresponding halides or benzyltriethylammonium salts: Synthesis, 688 (1979).

For use in the permanganate oxidation of benzylic positions, see Potassium permanganate, A12170.

The oxidation of primary alcohols to aldehydes by potassium chromate under phase-transfer conditions is better for higher homologues, where solubility in the aqueous phase is limited: Synthesis, 134 (1979). For phase-transfer catalyzed dichromate oxidation of secondary alcohols to ketones, see: Tetrahedron Lett., 1601 (1978).

For phase-transfer catalyzed conversion of nitriles to amides by alkaline H2O2, see: Synthesis, 243 (1980).
