1-diazo-2-oxoheptadecane, for example, the products of these two reactions are heptadecanoic acid and a surface-grafted long-chain ester. The latter can be removed as methyl heptadecanoate by ester exchange using methanolic HCl. Pronounced differences were observed between alumina, silica gel and fumed silica as supports, and were attributed to differences in the amount of adsorbed H2O and in the density of surface
研究了长链重氮酮与叠氮化物在无机固体上吸附的单分子层中的反应,并将其与空气-水界面中单分子层中的相应行为进行了比较。分离出的产物表明,光化学生成的中间体与共吸附水和固体表面的羟基均发生反应。例如,在1-重氮-2-氧杂十七烷的情况下,这两个反应的产物是十七烷酸和表面接枝的长链酯。后者可以通过使用甲醇的HCl进行酯交换而以十六烷酸甲酯的形式除去。在氧化铝,硅胶和气相二氧化硅作为载体之间观察到明显的差异,这归因于H 2吸附量的差异并在表面形成羟基密度的羟基。
