Solid‐state, room‐temperature stability for silabenzene 1 is granted by the bulky silane rendering kinetic inertness. Silabenzene 1 is synthesized in good yield from the crowded chlorosilane 2 with tert ‐butyllithium. The delocalized, aromatic nature of 1 was confirmed by NMR spectroscopy and the 1 J Si−C value, as well as calculations on an analogous silabenzene.
