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.

BiCl₃ + 3 C₆H₅MgBr₃ → Bi(C₆H₅)₃ + 3 MgBrCl

Structurally it resembles related compounds such as triphenylstibine. The C-Bi-C angles are 94°.

Triphenylbismuthine serves as a phenyl donor in some cross coupling reactions catalyzed by Pd(0) complexes. It reacts with trifluoromethanesulfonic acid to give bismuth triflate:

Bi(C₆H₅)₃ + 3 HO₃SCF₃ → Bi(O₃SCF₃)₃ + 3 C₆H₆

Triphenylbismuthine readily undergoes oxidative addition to form Bi(V) derivatives such as triphenylbismuthine dichloride.
