Triphenylstibine is the chemical compound with the formula Sb(C6H5)3, abbreviated SbPh3. This colourless solid is often considered the prototypical organoantimony compound. It is used as a ligand in coordination chemistry and as a reagent in organic synthesis.
SbPh3 was first reported in 1886, being prepared by the reaction:[1]
- 6 Na + C6H5Cl + SbCl3 → (C6H5)3Sb + 6 NaCl
The modern method employs the Grignard method, using phenylmagnesium bromide and SbCl3.[2]
