What is the mechanism of the reaction between Wagner's reagent and an alkaloids?

Wagner's reagent, which is an aqueous solution of iodine and potassium iodide, reacts with alkaloids containing nitrogen atoms to form a brown complex. This reaction is based on the oxidation of the nitrogen atoms in the alkaloids by iodine, resulting in the formation of the colored complex. The intensity of the brown color can be used to detect the presence of alkaloids in a given sample.


Why does Dragendorff's reagent form a yellow precipiate with alkaloids?

Dragendorff's reagent contains bismuth and potassium iodide. When it reacts with alkaloids, such as morphine or nicotine, a yellow precipitate is formed due to the formation of insoluble bismuth iodide complexes with the alkaloids. This reaction is commonly used to test for the presence of alkaloids in a sample.
