Novel Inorganic Ring Systems. XXIII. Hetero Spirosilazanes with Ge, Sn, and Zr in the Spiral CenterSymmetrical SiN-spiro[4,4]-nonanes of the skeleton composition Si5N4, Si4N4Ge, Si4N4Sn and Si4N4Zr and with the hetero atoms in the spiral center could be prepared for the first time in shape of their permethylated derivatives A1 to E1 via equations (1/2) as well as (3/4/5/6) respectively. They were confirmed in their structure by elemental analysis, proton n.m.r., mass, i.r., and Raman spectra.
Notes:
Symmetrische Silaza-spiro[4,4]-nonane der Gerüsttypen Si5N4, Si4N4Ge, Si4N4Sn und Si4N4Zr und mit den Heteroatomen als spiralen Zentren konnten in Form ihrer permethylierten Derivate A1 bis E1 über die Reaktionswege (1/2) bzw. (3/4/5/6) erstmalig dargestellt und in ihrer Struktur über Elementaranalyse, 1H-NMR, Massen-, IR- und Raman-Spektren eindeutig bestätigt werden.
