Investigation of the reactions of α-azidocarboxylic acids, N-(2-azidoethyl) amides and N-(2-azidoethyl) amines with trivalent P compounds shows that the intramolecular cyclization to spirophosphoranes of the intermediate phosphazo-compounds is typical of the azides of the first and third types but not of the second type. It is concluded that such cyclization is possible only where the functional group
研究α-叠氮基羧酸,N-(2-叠氮基乙基)酰胺和N-(2-叠氮基乙基)胺与三价P化合物的反应表明,中间体磷酸偶氮化合物分子内环化为螺磷phosph烷是叠氮化物的典型叠氮化物第一种和第三种,但不是第二种。结论是,仅当起始叠氮化物的官能团包含足够移动的氢原子或高度亲核的含质子的基团时,这样的环化才是可能的。已经开发了生产咪唑啉和恶唑啉的新的通用方法。
