Triphenylbismuthine is an organobismuth compound with the formula Bi(C6H5)3. It is a white, air-stable solid that is soluble in organic solvents. It is prepared by treatment of bismuth trichloride with phenylmagnesium bromide.[2]
- BiCl3 + 3 C6H5MgBr3 → Bi(C6H5)3 + 3 MgBrCl
Structurally it resembles related compounds such as triphenylstibine. The C-Bi-C angles are 94°.[3]
Triphenylbismuthine serves as a phenyl donor in some cross coupling reactions catalyzed by Pd(0) complexes.[4] It reacts with trifluoromethanesulfonic acid to give bismuth triflate:[5]
- Bi(C6H5)3 + 3 HO3SCF3 → Bi(O3SCF3)3 + 3 C6H6
Triphenylbismuthine readily undergoes oxidative addition to form Bi(V) derivatives such as triphenylbismuthine dichloride.[6]
