How is Diphenyliodonium chloride (CAS: 1483-72-3) typically synthesized?

Diphenyliodonium chloride is typically synthesized by the reaction of phenyllithium with iodine in an inert solvent such as THF. The process involves the formation of phenyl iodide, which then reacts with another equivalent of phenyllithium to form the diphenyliodonium ion. This ion then reacts with chloride to give the final product. The yield is generally high, and the reaction is carried out under anhydrous conditions.
