Iodination and iodo-compounds. Part III. Iodination of some aromatic nitro-compounds with iodine in 20% oleum

Abstract

The use of iodine in 20% oleum for the iodination of a range of aromatic nitro-compounds is described. The conditions necessary to achieve reaction and proof of the identities of the products are included. The system has been found to behave as an electrophilic reagent but it will not introduce and iodine atom ortho to a nitro-group.
