Ring Contractions of Octamethylcyclotetrasilazanes to Silyl‐Substituted Cyclotrisilazanes Reaction of the mono‐ and dilithium derivatives of bis(fluorsilyl)‐substituted cyclotetrasilazanes with fluorosilanes and fluoroboranes leads to ring contraction with formation of cyclotrisilazanes ( 1 – 8 ). The isomerisation is proved by the crystal structure determination of 1 and by NMR spectroscopy.
