Several new dioxaazasilacyclooctane derivatives have been prepared and their conformations studied by determination of their dipolemoments in solution or as neat liquids. The results indicate that the compounds are in conformational equilibrium, characterized by two extreme conformers, boat-boat (BB) and chair-chair (CC). In the BB conformer the existence of a Si ← N interaction is possible but this
