When 6- and 8-membered silazane rings are silylated after previous metalation with n-butyllithium isomerizations to cyclodisilazane structures take place by ring contraction. Structures of the various isomers are assigned by 1H-nmr.- and infrared spectra. The anionic rearrangements which were studied by proton nmr. spectroscopy and vapor-phase chromatography occur with catalytic amounts of base and
