Hexachlorodisiloxane, reacting with primary and secondary amines leads, dependent on stoichiometry, to numerous partially and totally organylamino substituted disiloxanes. Partially amino-substituted 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. See links below
