Why does replacement of dizonium ion by iodine not require cuprous halide ?
Asked by chahat | 20 Aug, 2010, 12:00: AM
Expert Answer
The replacement of diazonium ion is a nucleophilic substitution where the iodide ion (from KI) is the nucleophile so presence of cuperous halide is not required
In this reaction, catalysis by copper(I) is not mandatory, as iodide itself is easily and reversibly oxidizable and, thus, performs the function which copper(I) ions do in the Sandmeyer reaction.
