    Description / Table of Contents: Dimethyl-diphenyl and dimethyl-dibenzyl-silane react in liqu. NH3 in the presence of KKH2 giving rise to the formation of H2N—Si(Me2)—NH—Si(Me3)—NHK (III); exclusively C6H5 and C6H5CH2 are split off and substituted by NH2. Reaction of the potassium compound III with the equivalent amount of NH4Cl brings about a mixture of octamethylcyclotetrasilazane and hexamethylcyclotrisilazane.
    Notes: Dimethyl-diphenyl- und Dimethyl-dibenzyl-silan reagieren in flüss. NH3 in Gegenwart von KNH2 (Molverhältnis 1:0,55) unter Bildung von H2N—Si(Me2)—NH—Si(Me2)-NHK(III). Hierbei werden ausschließlich C6H5 als C6H6 und C6H5CH2 als Toluol abgespalten. Wird die Kaliumverbindung III mit der äquivalenten Menge NH4Cl in flüss. NH3 umgesetzt, so wird ein Gemisch von Octamethylcyclotetrasilazan und Hexamethylcyclotrisilazan erhalten.
