Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane ( P 2 H 4 ).
Phosphine oxide is the inorganic compound with the formula H 3 PO. Although stable as a dilute gas, liquid or solid samples are unstable. Although stable as a dilute gas, liquid or solid samples are unstable.
Phosphines or phosphanes are phosphorus compounds derived from phosphine and have the general structure R 3 P. For the nitrogen analogues, please see Category:Inorganic amines . Wikimedia Commons has media related to Phosphines .
The latter is a common feature of the chemistry of phosphorus. As a result, the lone pair of trimethylphosphine has predominantly s-character as is the case for phosphine, PH 3. [11] Tertiary phosphines are pyramidal. When the organic substituents all differ, the phosphine is chiral and
A metal-phosphine complex is a coordination complex containing one or more phosphine ligands. Almost always, the phosphine is an organophosphine of the type R 3 P (R = alkyl, aryl). Metal phosphine complexes are useful in homogeneous catalysis .
Compounds related to phosphine oxides include phosphine imides (R 3 PNR') and related chalcogenides (R 3 PE, where E = S, Se, Te). These compounds are some of the most thermally stable organophosphorus compounds. In general, they are less basic than the corresponding phosphine oxides, which can adduce to thiophosphoryl halides: [7]: 73
It is a tertiary phosphine. It is an oily liquid at room temperature, with a nauseating odor. It is an oily liquid at room temperature, with a nauseating odor. It reacts slowly with atmospheric oxygen , and rapidly with other oxidizing agents , to give tributylphosphine oxide.
The phosphonium structure is converted to phosphine oxide as the result of this reaction. [15] Phase-transfer catalysts and precipitating agents
