The first reported phosphine complexes were cis- and trans-PtCl 2 (PEt 3) 2 reported by Cahours and Gal in 1870. [5] Often the phosphine serves both as a ligand and as a reductant. This property is illustrated by the synthesis of many platinum-metal complexes of triphenylphosphine: [6] RhCl 3 (H 2 O) 3 + 4 PPh 3 → RhCl(PPh 3) 3 + OPPh 3 + 2 ...
Triphenylphosphine (IUPAC name: triphenylphosphane) is a common organophosphorus compound with the formula P(C 6 H 5) 3 and often abbreviated to P Ph 3 or Ph 3 P. It is versatile compound that is widely used as a reagent in organic synthesis and as a ligand for transition metal complexes, including ones that serve as catalysts in organometallic chemistry.

LiiP(C 6 H 5) 2 + CH 3 I → CH 3 P(C 6 H 5) 2 + LiI. Phosphine is a precursor to some tertiary phosphines by hydrophosphination of alkenes. For example, in the presence of basic catalysts PH 3 adds of Michael acceptors such as acrylonitrile: [7] PH 3 + 3 CH 2 =CHZ → P(CH 2 CH 2 Z) 3 (Z = NO 2, CN, C(O)NH 2)
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).

Triphosphane (IUPAC systematic name) or triphosphine is an inorganic compound having the chemical formula HP(PH 2) 2. It can be generated from diphosphine but is highly unstable at room temperature: [3] 2 P 2 H 4 → P 3 H 5 + PH 3. Samples have been isolated by gas chromatography. The compound rapidly converts to PH 3 and the cyclophosphine ...
