Chemistry of Silicon-Nitrogen Compounds, CLXVI: Organylamino Substitutions on Hexachlorodisiloxane

Article abstract of DOI:10.1007/BF00808949

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 of RR'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 deg C.
