Applications

Tetra-n-butylphosphonium bromide is used as a phase-transfer catalyst at high temperatures, at which nitrogen analogues tend to undergo elimination e.g. as catalyst for the dealkoxycarbonylation of malonates and ß-keto esters by heating in stearic acid. used as an ionic liquid solvent in the regioselective O-alkylation of C/O ambident nucleophiles. It is a synthetic reagent used in proteomics research.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. It is hygroscopic in nature.
