Bismuthinidene
WebFeb 27, 2024 · Abstract The long‐sought carbene–bismuthinidene, (CAAC)Bi (Ph), has been synthesized. Notably, this represents both the first example of a carbene‐stabilized subvalent bismuth complex and the extension of the carbene‐pnictinidene concept to a non‐toxic metallic element (Bi).
