The reaction of cyclic organobismuth compounds, 12-phenyl- and 12-chloro-5,6,7,12-tetrahydrodibenz[c,f][1,5]azabismocines, with Pt(PEt₃)₃ was examined. Oxidative addition of the exocyclic Bi–C bond to Pt(0) selectively took place in the reaction of the 12-phenyl derivative. Oxidative addition of the exocyclic Bi–Cl bond reversibly took place and was kinetically preferred, while endocyclic Bi–C bond oxidative addition products were thermodynamically favored and became the final products in the reaction of 12-chloro derivatives. These results demonstrate the oxidative addition of a Bi–C bond to a transition metal complex for the first time.

Bi-C键的氧化加成到Pt（0）：Pt（PEt3）3与环状有机铋化合物的反应

考察了环状有机铋化合物，12-苯基和12-氯-5,6,7,12-四氢二苯并[ c，f ] [1,5]氮杂双胍与Pt（PEt ₃）_3的反应。在12-苯基衍生物的反应中，有选择地将环外Bi-C键氧化加至Pt（0）。环外Bi-Cl键的氧化加成反应是可逆的，在动力学上是优选的，而环内Bi-C键的氧化加成产物在热力学上受到青睐，并成为12-氯衍生物反应的最终产物。这些结果首次证明了Bi-C键向过渡金属络合物的氧化加成。
