- Phosphonium abstract "The phosphonium (more obscurely: phosphinium) cation describes polyatomic cations with the chemical formula PR+4. Salts of the parent PH4+ are rarely encountered, but this ion is an intermediate in the preparation of the industrially useful tetrakis(hydroxymethyl)phosphonium chloride:PH3 + HCl + 4 CH2O → P(CH2OH)4+Cl−Organic phosphonium salts are common reagents in the laboratory. Those with a P-H bond are produced through protonation of phosphines:PR3 + H+ → HPR3+Many organic quaternary phosphonium cations (P+R4) are produced by alkylation of organophosphines. For example the reaction of triphenylphosphine with methyl iodide gives methyltriphenylphosphonium iodide, the precursor to a Wittig reagent:PPh3 + CH3I → CH3PPh3+I−The cation tetraphenylphosphonium (PPh4+) is a useful precipitating agent, analogous to quaternary ammonium salts used in phase transfer catalysis.".
