Two N-Aryl-Substituted Silyl Carbamates

Trimethylsilyl N-(4-bromophenyl)carbamate, C₁₀H₁₄BrNO₂Si, and trimethylsilyl N-tert-butyl-N-phenylcarbamate, C₁₄H₂₃NO₂Si, are both important silylating agents. The structures of both molecules are dominated by a plane containing a remarkably large number of atoms. The planes are organized by delocalization around the carbamate moiety. A quasi-pentacoordination of the Si atom in both compounds is also described.
