Summary
-
1.
By the double decomposition of disodium derivatives ofα,ω-polydimethylsiloxanediols with trichloromethylsilane, new organocyclosiloxanes containing silicon-attached chlorine were synthesized: chloropentamethylcylotrisiloxane and chlorohonamethylcyclopentasiloxane.

2.
By the double decomposition of the disodium derivatives ofα,ω-polysiloxanediols with butoxydichloromethylsilane, with butoxydichloromethylsilane, new organocyclosiloxanes containing a silicon-attached butoxy group were synthesized: butoxypentamethylcyclotrisiloxane, butoxynonamethylcyclopentasiloxane, and butoxyundecamethylcyclohexasiloxane.
-
3.
By the replacement of the chlorine of chlorononamethylcyclopentasiloxane by the amino group, nonamethylcyclopentasiloxanylamine was synthesized.
