| .3-Silylgruppenwanderung im Si2NSiN-Gerüst - Synthese und Molekülstruktur von 1.3-Diaza-2.4-disilacyclobutanen 1,3-Migration of Silylgroups in the Si2NSiN-System - Synthesis and Molecular Structure of l,3-Diaza-2,4-disilacyclobutanes  | | | Abstract
| N-Organylamino-N',N'-bis(trimethyl)amino-fluoroorganylsilanes react with butyl-lithium to give the corresponding lithium salts. Further reaction of these lithium salts with fluorosilanes leads to the formation of the expected substituted compounds. Diaza-disilacyclobutanes are formed by thermal LiF elimination in THF. The simultaneous 1,3-migration of a trimethylsilyl group from one nitrogen atom to another is demonstrated by the crystal structure determination of the products of two such reactions, with different substituent groups. | | |
