An unexpected cascade reaction for oxidation-oximization of cyclohexane with ammonium acetate was developed for the first time to access cyclohexanone oxime with 50.7% selectivity (13.6% conversion). Tetrahedral Ti sites in Ni-containing hollow titanium silicalite can serve as bifunctional catalytic centers in the reaction. This methodology not only provides a direct approach to prepare cyclohexanone oxime, but also simplifies process chemistry. Various available nitrogen sources, such as ammonium salt and even ammonia can be used as starting materials.

通过用乙酸铵对环己烷进行氧化-肟化来直接合成环己酮肟。

首次开发了出乎意料的级联反应，用乙酸铵将环己烷氧化-肟化，获得选择性为50.7％（转化率为13.6％）的环己酮肟。含镍的中空钛硅质岩中的四面体Ti位点可作为反应中的双功能催化中心。该方法不仅提供了制备环己酮肟的直接方法，而且简化了过程化学。各种可用的氮源，例如铵盐，甚至氨水，都可以用作起始原料。
