Abstract

Trimethylsilyl N-monoalkyl- and N, N-dialkyl-carbamates have been made in 85-95% yields by silylation of the corresponding ammonium carbamates with trimethylchlorosilane. Trimethylsilyl N N-dimethylcarbamate can be used for silylation of alcohols,phenols, and carboxylic acids. The silycarbamates react with carboxylic acid halides to give the corresponding acide amides. The reaction of trimethylsilyl carbamates with carboxylic anhydrides give the corresponding silyl carboxylate and acid amide, while the reaction with dicarboxylic anhydrides give the trimethylsilyl monoamide of the corresponding dicarboxylic acid, i.e. Me3SiO2-C{A figure is presented}CONR1R2.
