Synthesis and properties of silacyclobutylsilazanes

Ammonolysis of silacyclobutanes {ie305-01} (R=Cl, CH₃) gives silacyelobutane di- and polysilazanes. Reaction of the disilazane {ie305-02} with 1-chloro-1-methyl-1-silacyelobutane at 20–80° gives a trisilyl-substituted amine {ie305-03}. Trisilyl-substituted amines with one silacyclobutyl group, are obtained by reacting silacyclobutanes {ie305-04} (R=CH₃, C₆H₅). with sodium or potassium silylamides prepared from hexamethyldisilazane. It is shown that it is possible to obtain silylamides by reacting disilazanes directly with potassium metal at 90–100°.
