Cyclodisilazane mit verschiedenen Substituenten an allen vier ringgliedern

摘要

CyclodisilazanesC 1–8as well as open chained aminodisilazanesE 1–2with different substituents on each unit of the framework were synthesized according to Equ. (1)–(3) and (6) (a)–(d) repectively. In the case of Equ. (4) a spiro3.3trisilatetrazaneD1was formed instead ofC9. Eleven novel compounds of the three classes of substances are described in their properties (Tab. 1) and confirmed in their constitution by elemental analysis, nmr and mass spectra (Ta
