WebPotassium iodide (KI) is a chemical compound that can be used as an iodide ion source for nucleophilic displacement reactions. During the electrochemical oxidation of aldehydes, it acts as a mediator. In the presence of an acid, it can cleave some ethers. KI can iodinate aromatic and organothallium compounds in the presence of an oxidizing agent. Web× Close. The Infona portal uses cookies, i.e. strings of text saved by a browser on the user's device.
