Triaminoalkenes Derived from Cyclic (Alkyl)(amino)carbenes with a 1,1'-Ferrocenylene Backbone and N-Heterocyclic Carbenes: fcCAAC-NHC Heterodimers.

ABSTRACT: The study addresses triaminoalkenes derived from [3]ferrocenophane-type cyclic (alkyl)(amino)carbenes (fcCAACs) fc(CPh₂CNR) (fc = 1,1'-ferrocenylene) and N-heterocyclic carbenes (NHCs). Stable target compounds are obtained in good yields as crystalline solids by the combination of [fc(CPh₂CHNMe)][BF₄] with N,N'-dimethylimidazolin-2-ylidene and of [fc(CPh₂CHN-p-C₆H₄-tBu)](OTf) with 1,3,4,5-tetramethylimidazolin-2-ylidene, respectively, followed by treatment of the resulting addition product with KN(SiMe₃)₂. Due to the presence of a triaminoethene unit and a ferrocene moiety, four redox states are expected for such fcCAAC-NHC heterodimers, viz., electroneutral, mono-, di-, and tricationic. An invest
