The first silenolates with exocyclic structures [(Me<sub>3</sub>Si)<sub>2</sub>Si(Si<sub>2</sub>Me<sub>4</sub>)<sub>2</sub>SiC(R)O]<sup>-</sup>K<sup>+</sup> (<b>2a</b>: R = 1-adamantyl; <b>2b</b>: mesityl; <b>2c</b>: <i>o</i>-tolyl) were synthesized by the reaction of the corresponding acylcyclohexasilanes <b>1a</b>-<b>c</b> with KO<i>t</i>Bu. NMR spectroscopy and single-crystal X-ray diffraction analysis suggest that the aryl-substituted silenolates <b>2b</b>,<b>c</b> exhibit increased characte ...[more]
