Synthesis bismuthides

In contrast, the synthesis of monomeric stibides and bismuthides R2MER2 failed until we recently introduced an alternative, generally applicable pathway for the synthesis of monomeric group 13/15 compounds. We found that heterocycles may generally serve as starting compounds for the generation of their monomeric forms. In accordance with their formulation as head-to-tail adducts , strong Lewis bases are able to cleave the... 

While the systems with the 3p, 4p, and 5p main group elements have been investigated in detail, less information is available for the thallides, plumbides, and bismuthides. This is largely due to synthesis problems, since these elements...
