Ringschlußversuche mit Phenylborsäure / Attempts for Synthesis of Inorganic Rings with Phenylboric Acid

Abstract

Abstract The inorganic ring systems BNCO2Si2 (B) and BCO3Si4 (E) were prepared for the first time via equations (1) and (5), system BCO3Si2 (C) enlarged by preparation of compound C 1 via eq. (4). Synthesis of a system BCO2Si2 (D) failed as well as preparation of five and seven membered building units VI and VIII. For bis(trimethylsiloxy)phenylborane (IX) detailed and additional information about preparation, properties and structure analysis is given. Compound VTI, C5H15NOSi, was obtained for the first time via eq. (7) and described in its properties.
