Conclusions

  1. 1.

    The reaction ofα,ω-dichlorodimethylsiloxanes with from two to ten silicon atoms in the chain with methylamine has been studied and it has been established that when a solution of the chloride is added to the methylamine at −60°C the reaction takes place with the formation of only α,ω-bis(methylamino)dimethylsiloxanes.

     
  2. 2.

    The aminolysis of 1,3-dichlorotetramethyldisiloxane by the addition of a solution of the chloride to a solution of methylamine in high dilution and subsequent boiling gives a 60% yield of N,N′-dimethyloctamethylcyclotetrasil-4,8-diaza-2,6-dioxane.

     
  3. 3.

    Heating 1,5-bis(methylamino)hexamethyltrisiloxane with an ammonium sulfate catalyst has given N-methylhexamethylcyclotrisilazadioxane.
