The reaction of lithium N-trimethylsilyl-amides of the type RN(SiMe3)Li with bismuth(iii) chloride yielded mono-, di- or triaminobismuthanes depending on the sterical demand of the anilide ligand R and the used stoichiometry. For the bulky Mes* substituent the reaction with BiCl3 resulted in the formation of a C-C coupling product as the main product besides a small amount of the expected Mes*N(SiMe3)BiCl2.
RN(SiMe₃)Li型的N - 三甲基硅基锂酰胺与氯化铋(iii)反应，根据酰苯胺配体R的空间需求和所使用的化学计量比，生成单氨基、二氨基或三氨基铋烷。对于庞大的Mes取代基，与BiCl₃的反应除了生成少量预期的MesN(SiMe₃)BiCl₂外，还生成一种C - C偶联产物作为主要产物。
