ChemInform Abstract: Ring Contractions of Octamethylcyclotetrasilazanes to Silyl‐Substituted Cyclotrisilazanes.

In contrast to the formation of acyclic silazanes on reaction of (I) or its Li salts with various reagents caused by the easy cleavage of the Si‐N bond, their reaction behavior toward fluorosilanes and ‐boranes is different.
