  Synthese von amin- und chlorfunktionalisierten Cyclotrisiloxanen mit dem Hilfsreagenz Hexaethyldistannoxan

  摘要：

  The interaction of cyclodisilazandichloro compound 1 with hexaethyldistannoxane 2 first leads at room temperature to the substitution of one chlorine atom by a triethylstannoxane group. At higher temperature, the second chlorine atom is also replaced by a stannoxane group. The reaction of 1 with two equivalents of 2 results in the distannoxanebis(amino)silane 4 and is carried out without solvent so that the formed chlortriethylstannane can be removed easily under reduced pressure after completion of the reaction. By treatment of 1,3-dichloro-1,1,3,3-tetramethyl-disiloxane 5 and 1,1,1,3,3,3-hexachlor-disiloxane 6 with the silyldistannoxane compound 4 the cyclotrisiloxanes 7 and 8 are obtained. In addition to the common characterisation methods, 7 and 8 have also been subject to single crystal X-ray analyses revealing two similar almost planar Si3O3 six membered cycles. The mean Si-O bond lengths within the cycles [Si-O 1.632(13) (7) and 1.619(22) Angstrom (8)] are a function of the different electronegativities of the silicon substituents.
