Tetrabutylphosphonium chloride is a green organic compound with a wide range of uses in catalysis, flame retardancy, solubility, ionic liquids and electroplating.
(1) As a catalyst for organic synthesis, it can be used to prepare alkyl bromides, 2-amino-4H-chromium derivatives, and methyl ester compounds.
(2) As a flame retardant additive for vinyl resins and chloroprene rubber, it is used to reduce the flammability and smoke emissions of these materials.
(3) As an ionic liquid, it provides a phosphorus source for microwave-driven synthesis of nickel phosphide nanoparticles, which are then used for efficient hydrogen evolution reactions.
(4) As an electroplating agent for various metals (such as copper, nickel, zinc, tin, lead, silver, gold, platinum, palladium and their alloys) to enhance the corrosion resistance and mechanical properties of metal coatings.
