Triphenylphosphine/CAS: 603-35-0
Description:
Triphenylphosphine: a member of tertiary phosphines
Triphenylphosphine (TPP) is a member of tertiary phosphines, which is phosphane, in which the three hydrogens are replaced by phenyl groups. It has a role as a reducing agent and an NMR chemical shift reference compound. It is a crucial ligand utilized in the Wittig reaction for alkene synthesis. This reaction involves the formation of alkyliden-etriphenylphosphoranes from the action of butyllithium or another base on the quarternary halide. Triphenylphosphine is used to synthesise organic compounds due to its nucleophilicity and reducing character.

Usage
Triphenylphosphine is first sulfonated with oleum to form the trisulfonic acid.
Triphenylphosphine can be used in Wittig synthesis. It is a standard ligand in homogeneous catalysis.
Triphenylphosphine is used in the synthesis of an organophosphorus intermediate, trimethyl phosphite in ester exchange method. And then a series of organophosphorus pesticides such as dichlorvos, monocrotophos and phosphamidon can be further obtained.
In addition, it can be used as stabilizers in the synthesis of rubber and resins, antioxidants in polyvinyl chloride, and raw material in the synthesis of alkyd resins and polyester resins.
