    Notes: Summary Reaction of hexachlorodisiloxane with primary and secondary amines leads — in dependence of stoichiometry — to numerous partially and totally organylamino substituted disiloxanes. Partially aminosubstituted chlorodisiloxanes are very sensitive to moisture and can be converted into disiloxanes with different organylamino groups. Exhaustive alkanolysis substitutes amino as well as chloro groups giving hexaalkoxydisiloxanes, but partial alkanolysis may substitute amino in preference to chloro groups. Mass spectra can be interpreted by abstraction ofRR′N·,RR′N+,RR′NH and (RR′N minus H) units. Most of the compounds are colourless liquids but hexakis(piperidino)-disiloxane melts at 270 °C.

    Notes: Abstract CyclodisilazanesC 1–8 as well as open chained aminodisilazanesE 1–2 with 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 spiro[3.3]trisilatetrazaneD1 was 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 (Tab. 2–3).
