| Abstract: | Zusammenfassung Verbindungen des Typs R2NBCIN(Sime
3)2
* (R=C2H5,iC3H7, C6H11, C6H5) bleiben bis zu hohen Temperaturen beständig. Sie reagieren jedoch mit NaN(Sime
3)2 unter Übertragung einer Methylgruppe von einem Silicium-zu einem Boratom zu N,N -Bis(trimethylsilyl)-tetramethylcyclodisildiazan und R2NBmeN(Sime
3) (R=C2H5,iC3H7).
Compounds of the type R2NBClN(Sime
3)2
* were prepared. (R=C2H5,iC3H7, C6H11, C6H5. They do not show any tendency to condense thermally under elimination of trimethylchlorosilane. When these silylaminoboranes were allowed to react with NaN(Sime
3)2, complicated rearrangements were observed. The compounds in which R=C2H5 oriC3H7 rearranged under formation of N,N-bis(trimethylsilyl)-tetramethylcyclodisildiazane and R2NBmeN(Sime)2. In this reaction a migration of a methyl group from silicon to boron occurs. |
