Stable vinylidene analogue : The synthesis of the first representative of a new compound class of low‐valent Group 14 elements, namely silagermenylidene A , is achieved by reduction of Tip 2 SiCl 2 and NHC⋅GeCl 2 (Tip=2,4,6‐ i Pr 3 C 6 H 2 ; NHC=1,3‐diisopropyl‐4,5‐dimethylimidazol‐2‐ylidene). The potential of A as a synthon is demonstrated by the formal [2+2] cycloaddition with phenylacetylene to afford NHC‐stabilized cyclic germylene B .
