Abstract
1,2,2-Trimethyldisilane-1,1,2-triol (1) is formed as an unstable intermediate upon hydrolysis of oligo(trimethyldisilanylsesquiazane). In the absence of trapping agents it undergoes rapid condensation to give ether-soluble poly(trimethyldisilanyloxane) which contains silanol groups. Treatment of the hydrolysis products with chlorotrimethylsilane in the presence of triethylamine affords trimethylsiloxy derivatives, (Me3SiO)2MeSiSiMe2(OSiMe3),5,6, and [Si2Me3O x (OSiMe3) y ] n . The isolation of these products indicates that disilanetriol1 readily undergoes condensation to form hydroxylcontaining six-membered rings and polysiloxanes. The condensation of compound1 in the presence of Me3SiOH has been studied. The ratio between the isomeric cyclosiloxanes5 and6 has been determined both by1H NMR spectroscopy and by a chemical method (chlorinolysis).
