Phosphonium ion Structure of PH + 4, the parent phosphonium cation. In chemistry, the term phosphonium (more obscurely: phosphinium) describes polyatomic cations with the chemical formula PR + 4 (where R is a hydrogen or an alkyl, aryl, organyl or halogen group). These cations have tetrahedral structures.
Most processes begin with phosphorous acid (aka phosphonic acid, H 3 PO 3), exploiting its reactive P−H bond. [1] [3]Phosphonic acid can be alkylated via the Kabachnik–Fields reaction or Pudovik reaction to give aminophosphonate, which are useful as chelating agents.
Phosphonium iodide is a powerful substitution reagent in organic chemistry; for example, it can convert a pyrilium into a phosphinine via substitution. [3] In 1951, Glenn Halstead Brown found that PH 4 I reacts with acetyl chloride to produce an unknown phosphine derivative, possibly CH 3 C(=PH)PH 2 ·HI .
Spanish fly isn’t just ineffective as an aphrodisiac — it’s also dangerous. So keep Spanish fly and other herbal aphrodisiacs at arm’s length. There’s just way too much at stake.

Tetraphenylphosphonium chloride is the chemical compound with the formula [(C 6 H 5) 4 P]Cl, abbreviated Ph 4 PCl or PPh 4 Cl or [PPh 4]Cl, where Ph stands for phenyl. Tetraphenylphosphonium and especially tetraphenylarsonium salts were formerly of interest in gravimetric analysis of perchlorate and related oxyanions.
