Abstract

Abstract: To get more information about the reactivity profile of the donor‐stabilized guanidinatosilylene [ArNC(NMe2 )NAr]Si[N(SiMe3 )2 ] (1 ; Ar = 2, 6‐diisopropylphenyl), a series of test reactions was studied. Thus, treatment of1 with Me3 SiN3, (PhO)2 P(O)N3, PhC(O)Ph, Me–C≡C–C≡C–Me, Ph–C≡C–C≡C–Ph, CO2, CS2, ZnCl2, or ZnEt2 yielded the respective products9 –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 compounds9 –17 is based on oxidative addition reactions (for9 –15 ) or Lewis acid/base reactions (for16 and17 ). In most cases, these typical silylene reactions are coupled with additional reactivity facets, which are correlated with the guanidinato or bis(trimethylsilyl)amido ligand of1 . According to these studies, silylene1 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. Abstract : The silylene [DippNC(NMe2 )NDipp]Si[N(SiMe3 )2 ] (Dipp = 2, 6‐diidopropylphenyl) proved to be a very useful building block with a high synthetic potential for the preparation of new silicon(IV) and silicon(II) compounds (see examples1 –9 ).
