Application
The applications of Triphenylphosphine oxide(TPPO) mainly include the following fields:
Organic synthesis:
TPPO participates as an intermediate in drug synthesis, alcohol oxidation, halogenated hydrocarbon substitution and other reactions, such as catalyzing the oxidation of alcohols to form aldehydes or ketones, or a variant of Wittig reaction (aza Wittig reaction).
Pharmaceutical field:
TPPO, as a pharmaceutical intermediate, participates in drug synthesis, such as the preparation of anticancer drugs or cardiovascular drugs.
Catalyst:
TPPO is commonly used as a ligand for metal catalysts, such as palladium catalysts (such as Pd (PPh3) ₄), to construct carbon carbon bonds in coupling reactions with a yield of up to 90%.
Extractant:
TPPO is used for the extraction and separation of metals or organic compounds.
Flame retardant:
TPPO, as a halogen-free flame retardant, is compounded with bisphenol A phosphate esters to enhance the flame retardancy of polymers such as PC/ABS and PETG, while maintaining high light transmittance.
