The cover picture shows an obvious approach for the synthesis of ferrocene‐based N‐heterocyclic silylenes, namely the reduction of suitable silicon(IV) precursor compounds. This strategy is commonly applied for N‐heterocyclic silylenes in general, whereas for the heavier analogues divalent precursors like [GeCl 2 (1,4‐dioxane)] and MCl 2 (M = Sn, Pb) are readily available and therefore widely used. We have studied the suitability of silicon(IV) dihalides in this context (the molecular structures of two representative examples are shown). Unfortunately, our attempts were met with limited success. It remains unclear whether this reductive approach is applicable to our system. More details are discussed in the article by Jan Oetzel, Clemens Bruhn, and Ulrich Siemeling on page 935 ff .
