THF中3与n -杂环碳({（Me)CN(i-Pr)}2C:）的1:1反应生成配体取代产物4，而对应的1:1反应（在H2O存在下）得到第一个具有结构特征的锗三（二硫烯）离子5为主要产物，“裸”二硫烯自由基6˙为次要副产物。通过实验和理论方法对4和5的结构和键合进行了探讨。我们的研究表明，碳介导的部分水解可能是一种获得主基团元素三（二噻吩）配合物的新方法。
While the 1 : 1 reaction of 3 with an N-heterocyclic carbene ({(Me)CN(i-Pr)}2C:) in THF resulted in ligand-substituted product 4, the corresponding 1 : 2 reaction (in the presence of H2O) gives the first structurally characterized germanium tris(dithiolene)dianion 5 as the major product and the “naked” dithiolene radical 6˙ as a minor by-product. The structure and bonding of 4 and 5 were probed by experimental and theoretical methods. Our study suggests that carbene-mediated partial hydrolysis may represent a new method to access tris(dithiolene) complexes of main-group elements.
