%X Aromatic ethers are rapidly iodinated when treated in alcoholic solution with iodine and hydrogen peroxide in the presence of a strong mineral acid. High yields of the mono-iodo-derivatives are obtained with anisole and the 2-naphthyl ethers whilst both mono- and diiodination occur readily with the dimethoxybenzenes. In the absence of a mineral acid the reaction is very slow and only poor yield of the iodo-ethers result.   A convenient process is described for the preparation of p-chloro- and p-bromo- anisole, and other chloro- and bromo-ethers, the ether being treated with hydrochloric acid and with potassium bromide and sulphuric acid respectively in the presence of hydrogen peroxide.
