  Six‐Membered N‐Heterocyclic Carbenes with a 1,1′‐Ferrocenediyl Backbone: Bulky Ligands with Strong Electron‐Donor Capacity and Unusual Non‐Innocent Character

  摘要：

  AbstractThe stable, crystalline N‐heterocyclic diaminocarbene fc[N(CH2tBu)‐C‐N(CH2tBu)] (2d, fc = 1,1′‐ferrocenediyl) was prepared by deprotonation of its formamidinium precursor fc[N(CH2tBu)‐CH‐N(CH2tBu)][BF4] (1d) and used for the preparation of the 16 valence electron complexes [Mo(2d)(CO)4], [RhCl(2d)(cod)] (cod = 1,5‐cyclooctadiene) and [RhCl(2d)(CO)2]. 1d, 2d and [RhCl(2d)(cod)] were structurally characterised by single‐crystal X‐ray diffraction studies. The electrochemical properties of 2d, its 2‐adamantyl analogue 2c, its complex [RhCl(2d)(CO)2] and of the precursors 1d and 1,1′‐bis(neopentylamino)ferrocene were investigated by electrochemistry. The carbenes are easily oxidised to the corresponding radical cation, whose persistent nature is unprecedented in the chemistry of N‐heterocyclic carbenes. The spin density is located at the Fe atom and the carbene C atom according to the results of EPR spectroscopic studies and DFT calculations.(© Wiley‐VCH Verlag GmbH & Co.

  contrast, the cyclic (alkyl)(amino)carbene 1-(2,6-diisopropylphenyl)-3,3-diethyl-5,5-dimethylpyrrolidin-2-ylidene (CAACEt) gave rise to a stable adduct only with ph(NSiMe3)2Pb. The ferrocene-based N-heterocyclic olefin fc(NCH2tBu)2CCH2 was synthesised. It afforded a stable adduct with triphenylborane, but not with the diaminoplumbylenes of this study. All stable adducts were structurally characterized

  摘要这项研究的目的是更多地揭示N-杂环烯烃作为碳供体配体对二价14族元素化合物的配位/稳定作用的潜力。N-杂环烯烃1,3,4,5-四甲基-2-亚甲基咪唑啉（MeIMeCH2）的稳定加合物与环状二氨基p ph（NSiMe3）2Pb（ph = 1,2-亚苯基）和fc（NSiRMe2）2Pb分离（fc = 1,1'-二茂铁基； R = Me，tBu）以及非环状同系物[（Me3Si）2N] 2Pb。相反，环状（烷基）（氨基）卡宾1-（2,6-二异丙基苯基）-3,3-二乙基-5,5-二甲基吡咯烷基-2-亚基（CAACEt）仅与ph（ NSiMe3）2Pb。合成了基于二茂铁的N-杂环烯烃fc（NCH2tBu）2CCH2。它提供了与三苯基硼烷的稳定加合物，但没有与本研究的二氨基lum形成加合物。所有稳定的加合物均通过单晶X射线衍射进行结构表征。对于二氨基p加合物，发现Pb-C键载体相对于PbN2平面基本垂直的取向。207Pb
