氨甲酰基硅烷可以与硝酮反应,合成α-(N′-甲基-N′-三甲基硅氧基)氨基-N,N-二甲基苯乙酰胺(5).经研究发现,该产物具有互变异构现象,提出了这一互变异构体的结构,并通过1HNMR谱在不同温度(55~-30℃)下的数据,证实了指定结构的存在:在55℃时,呈现结构(5)的形式;而在-30℃时,呈现结构(8)的形式,它们互变的中间体结构则在55~-30℃之间随温度的变化而变化.
The carbamoyl silane can react with nitrones to synthesize α- (N’-methyl-N’-trimethylsiloxy) amino-N, N-dimethylphenylacetamide (5) The product has the tautomerism, the structure of this tautomer is proposed, and the data of the 1H NMR spectrum at different temperatures (55 to -30 ° C) confirm the existence of the indicated structure: at 55 ° C (5), while at -30 ℃, the structure of structure (8) appears. The intermolecular intermediate structure changes with the temperature between 55 ℃ and -30 ℃.
