Silyl group at the nitrogen atom in the O -silylurethanes drastically affects the thermolysis processes and allows one to simplify the synthesis of methyl- and trimethylsilyl isocyanates.
New N-siloxy- or N-alkoxy-carbamic acidderivatives have been prepared. The crystal structure of N-siloxy-O-tert-butyl carbamate was determined. The thermal behaviour of these compounds was studied in the absence and in the presence of other reaction partners. The reaction products were identified by gas chromatography, gas chromatography-mass spectroscopy, IR spectroscopy and NMR. The experimental
