    摘要: Methods and kits for preventing or minimizing the formation of isatin oximes during formation of an isatin from an isonitrosoacetanilide are provided. Also provided are methods and kits for preventing or minimizing the formation of isatin oxime impurities after formation of an isatin from an isonitrosoacetanilide by using a decoy agent in the quenching and/or extraction steps. The isatins can be prepared using a decoy agent and desirably a strong acid. Further provided are methods for preparing isatin oximes.
