New N-siloxy- or N-alkoxy-carbamic acid derivatives 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
已经制备了新的N-甲硅烷氧基-或N-烷氧基-氨基甲酸衍生物。测定了N-甲硅烷氧基-O-氨基甲酸叔丁酯的晶体结构。在不存在其他反应伙伴的情况下研究了这些化合物的热行为。通过气相色谱,气相色谱-质谱,IR光谱和NMR鉴定反应产物。实验结果可以通过用质谱法检测到的自由基型过渡态(羧基氮化物)的形成来解释。
