To get more information about the reactivity profile of the donor‐stabilized guanidinatosilylene [ArNC(NMe 2 )NAr]Si[N(SiMe 3 ) 2 ] ( 1 ; Ar = 2,6‐diisopropylphenyl), a series of test reactions was studied. Thus, treatment of 1 with Me 3 SiN 3 , (PhO) 2 P(O)N 3 , PhC(O)Ph, Me–C≡C–C≡C–Me, Ph–C≡C–C≡C–Ph, CO 2 , CS 2 , ZnCl 2 , or ZnEt 2 yielded the respective products 9 – 17 , all of which were characterized by elemental analyses, NMR spectroscopic investigations in the solid state and in solution, and single‐crystal X‐ray diffraction studies. The formation of compounds 9 – 17 is based on oxidative addition reactions (for 9 – 15 ) or Lewis acid/base reactions (for 16 and 17 ). In most cases, these typical silylene reactions are coupled with additional reactivity facets, which are correlated with the guanidinato or bis(trimethylsilyl)amido ligand of 1 . According to these studies, silylene 1 proved to be a very useful building block with high synthetic potential for the preparation of new silicon(IV) and silicon(II) compounds, with quite novel structural motifs.
