Tóm tắt

The electrochemical behaviour of cyclic polysilanes, namely, hexamesitylcyclotrisilane (Mes2Si)3 (I), 1,2,3,4-tetra-tert-butyltetramethyl-cyclotetrasilane [t-Bu(Me)Si]4 (II), decaethylcyclopentasilane (Et2Si)5 (III), decapropylcyclopentasilane (Pr2Si)5 (IV), dodecamethylcyclohexasilane (Me2Si)6 (V), tetradecaethylcycloheptasilane (Et2Si)7 (VI), hexadecamethylcyclooctasilane (Me2Si)8 (VII) and octadecamethylcyclononasilane (Me2Si)9 (VIII), have been studied by cyclic voltammetry and preparative scale electrolysis. The effects of electrolyte, ring size and nature of substitutes both on oxidation peak potential and upon reactivity as well as style of product are discussed.
