Notes:
[Me2SiNBFN(SiMe3)2]3 (1) is synthesized in the reaction of trilithiated hexamethylcyclotrisilazane with F2BN(SiMe3)2. The mono- and dilithium derivatives of the six-membered ring (Me2SiNH)2 Me2SiNSiFMe2 react with the F2B-substituted cyclotrisilazane F2B(NSiMe2)3(SiFMe2)2 in the molar ratio 1:1 or 1:2 to give the BF-coupled rings 2 and 3. The crystal structure analysis of 1 and 3 and pyrolysis of 1 and 3 with formation of silicon boron carbonitride and its crystallisation to composite powders at very high temperatures are reported.
