Solvolysis of trimethylsilyl-N-aryl carbamates

Converting Carbon Dioxide into Carbamato Derivatives

“…The mechanism of reaction of some trimethylsilylcarbamates with 2-propanol or 2-methylbutan-2-ol has been studied . It has been suggested that the reaction proceeds via nucleophilic attack of ROH to the silicon atom of the carbamato group.…”

Formation of Aromatic O‐Silylcarbamates from Aminosilanes and Their Subsequent Thermal Decomposition with Formation of Isocyanates

“…[9] Another synthesis pathway was investigated by Kozyukov et al By heating aniline and different O-and N-silylcarbamates for several hours the desired product could be obtained in yields of up to 40 %. [10] Knausz et al [11] and the research group of Belova [12] were able to synthesize compound 1 a in yields of up to 45 % by mixing aniline with CO 2 /hexamethyldisilazane, a so called N-siloxycarbonylating reagent, either for a longer period or by heating to 60°C for a few hours. Similar systems include CO 2 /hydridosilane and CO 2 / N,N'-bis(trimethylsilyl)carbodiimide.…”
