title: Synthesis and Properties of an Overcrowded Silabenzene Stable at Ambient Temperature.
abstract: 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.
