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). The bonding has been investigated by single-crystal X-ray diffraction studies and DFT calculations. This report also highlights the hitherto unknown reducing and ligand transfer capability of a beryllium(0) complex.
人们合成了长期以来备受关注的卡宾-铋亚基化合物 (CAAC)Bi(Ph)。值得注意的是，这不仅是首例卡宾稳定的低价铋配合物，也是卡宾-磷属元素化合物概念向无毒金属元素（铋）的拓展。该配合物的成键性质通过单晶 X 射线衍射研究和 DFT 计算进行了研究。本报告还强调了一种铍(0)配合物迄今为止未知的还原和配体转移能力。
