Triphenylstibine was first reported in 1886, being prepared from
antimony trichloride and
chlorobenzene: :6 Na + 3 C6H5Cl + SbCl3 → (C6H5)3Sb + 6 NaCl In an alternative method,
phenylmagnesium bromide is treated with SbCl3. Upon treatment with
antimony trichloride, triphenylstibine undergoes a
redistribution reaction: :
Stiboranes can be synthesised from triphenylstibine by halogenation: : As confirmed by
X-ray crystallography, features pentacoordinate Sb(V) with trans-diaxial chloride ligands. ==References==
