Silazane-containing ring compounds

In the present research program, which is directed to synthesizing useful polymers from silazane containing ring compounds, three general pathways were followed ... 

In a research program to explore the possibilities of synthesizing useful polymeric materials from silazane (Si-N) containing ring compounds, reactions of the following ring systems were studied ... 

It is also possible to form novel polysilazanes by dehydrocyclodimerization of the ammonolysis product of CH3SiHCl2, or coammonolysis products of this silane with other chlorosilanes.33 Ring compounds that contain the desired Si and N atoms may also be used as starting materials, followed by hydrolysis, thermolysis, polymerization, or copolymerization to convert them into silazane-type materials. Examples are cyclic bis (silyl) imidates, /V-acylcyclosilazoxanes, /V-arylcyclosilazoxanes, and A,A,-diarylcyclosilazanes.34...
