On polymerization of organosilicon cyclic compounds
The chemistry of organosilicon cyclic compounds has been vigorously developed. The interest in this field of organosilicon chemistry is due to the exceptionally wide synthetic possibilities and investigations on the structure and properties of cyclic systems. The high reactivity of the cycle in various rearrangements and polymerizations offers unlimited possibilities of synthesizing and investigating the macromolecules of elemento-organic polymers (metalorganic polymers). The polymerization reaction of cyclic organosilicon compounds gains further theoretical and practical interest also for the reason that this is one of the most significant ways for synthesis of oligomers and high molecular compounds with inorganic and organo-inorganic chains in the molecule. It would be impossible for such a report to consider the widespread investigations made in this field of organosilicon chemistry, therefore, I will restrict myself to rearrangements and polymerization reactions examplified by representatives of two classes of cyclic compounds: organocyclosiloxanes and organocyclosilazanes.
