  AbstractReaction of Et2NSi(SiMe3)3 with potassium tert‐butoxide gives the silylenoid Et2N(Me3Si)2SiK. Structural characterisation and reactivity of this compound was studied. It was found that while Et2N(Me3Si)2SiK exhibits the typical NMR spectroscopic properties for a silylenoid species it does not undergo self‐condensation under ambient conditions. Its reaction with zirconocene and hafnocene dichlorides gave the expected silyl metallocene chloride. However, there seems to be no strong interaction between the amino nitrogen atom and the group‐4 metal. Besides the synthesis of Et2N(Me3Si)2SiK also the preparation of the related silylenoid compound (Et2N)2(Me3Si)SiK and was accomplished. (© Wiley‐VCH Verlag GmbH & Co.

  Synthesis, properties, and reactions of various alkynyl oligosilanes, and their potassium derivatives are described. A series of tris(trimethylsilyl)silylalkynes have been prepared. Their reaction with potassium tert-butoxide leads to the corresponding potassium derivatives, which can be subjected to further derivatization. X-ray structures of three oligosilylalkynes are reported. (© Wiley-VCH Verlag

  Persilylcyclotetrasilanes of the type [(R1R2R3Si)2Si]4 (R1 = R2 = R3 = Me; R1 = Et, R2 = R3 = Me) were readily obtained by the reductive coupling of the corresponding 2,2-dibromo-1,1,1,3,3,3-hexaalkyltrisilanes using sodium; the Si4 frameworks of these persilyl compounds act as much more intense chromophore than those of peralkyl analogues.
