Ring Contraction in the Cyclotrisilazane System - Synthesis and Molecular Structures of Silyl-Bridged Cyclodisilazanes

1-(Fluorodiorganylsilyl)-2,2,4,4,6,6-hexamethyl-3-(trimethylsilyl)cyclotrisilazanes react with butyllithium to give the corresponding lithium salts.Ring contraction of the lithium salts with formation of lithiated (fluorodiorganylsilyl)amino-substituted four-membered rings is observed in THF solution.The dimerisation of these cyclodisilazanes with elimination of LiF is demonstrated by crystal structure determinations of three products.Monoclinic and triclinic crystalline modifications of one compound could be isolated. - Keywords: Cyclotrisilazanes, Ring Contraction, Cyclodisilazanes, Crystal Structures
