Tetraphenylphosphonium Phenolate 60% CAS#15464-47-8

Triphenylphosphine oxide
Phosphonium salts, structurally similar to quaternary ammonium salts, have a phosphorus atom with a larger atomic radius than nitrogen, resulting in stronger polarization effects compared to quaternary ammonium salts. Main applications: Precursor for phosphonium ylides in Wittig reactions in fine chemicals, pharmaceuticals, and liquid crystal monomer synthesis; curing accelerator in polymer polymerization; phase transfer catalyst in organic synthetic chemistry.
