基于二茂铁的路易斯碱作为金属配体在各种各样的应用中得到了广泛的应用。然而，二茂氰化物的配位化学尚未得到充分的研究。在此，我们描述了一种新的合成方案生成氰二茂物。研究了这些金属配体与[Cu(NCMe)4][PF6]、[(PPh3)2Cu(NCMe)2][PF6]和[(dppf)Cu(NCMe)2][PF6]盐的配位化学，为1,2 '-和1,2-二氰二茂络合物的簇状和聚合形式提供了晶体学证据。研究发现，配合物的稳定性和配体的解离对溶剂有很强的依赖性。
Ferrocene-based Lewis bases have found utility as metalloligands in a wide variety of applications. The coordination chemistry of cyanoferrocenes however, is underexplored. Herein, we describe a new synthetic protocol for the generation of cyanoferrocenes. The coordination chemistry of these metalloligands to [Cu(NCMe)4][PF6], [(PPh3)2Cu(NCMe)2][PF6] and [(dppf)Cu(NCMe)2][PF6] salts has been explored, providing crystallographic evidence of cluster and polymeric forms of 1,1'- and 1,2-dicyanoferrocene complexes. The stability of the complexes and ligand dissociation were found to be strongly solvent-dependent.
