Abstract: | 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. |
