摘要：

Triarylbismuthanes bearing three different aryl groups, (ArArArBi)-Ar-1-Ar-2-Bi-3 (4), have been conveniently synthesized by the action of aryl Grignard reagent Ar-3- MgBr on unsymmetrical diarylbismuth triflate-HMPA complexes Ar(1)Ar(2)BiOTf(HMPA)(2) (8), Which are readily accessible by the selective cleavage of triarylbismuthanes (Ar2ArBi)-Ar-1-Bi-2 (7; Ar-1 is more fugacious than Ar-2) with trimethylsilyl triflate in, the presence of HMPA.
