Conclusions

  1. 1.

    The hydride addition of dihydrosiloxanes to methylvinylcyclosiloxanes in the presence of catalytic amounts of H2PtCl6 was studied and it was shown that at a 1∶2 mole ratio the end reaction products are organobicyclosiloxanes with carbosiloxane groups between the rings.

     
  2. 2.

    The dihydrosiloxanes add to the double bond not only in the β position but also in part in the α position, relative to the silicon atom in the ring.

     
  3. 3.

    The rate of hydride addition to heptamethylvinylcyclotetrasiloxane decreases with increase in the length of the siloxane chain in the dihydrosiloxanes and decrease with temperature.
