Galli, Carlo published the artcileAromatic iodination: evidence of reaction intermediate and of the σ-complex character of the transition state, Related Products of iodides-buliding-blocks, the main research area is aromatic iodination mechanism reaction intermediate; transition state aromatic iodination.
The reactivity of four different procedures of aromatic iodination is compared under the same exptl. conditions, and their selectivity toward two substrates in competition, i.e., mesitylene (I) and durene (II), is evaluated. Two of these procedures, namely, S2O82-/I2 and CeIV/I2, present strong oxidizing capacity. Since the same I/II relative reactivity is obtained from the four procedures, it becomes possible to state that a common reactive intermediate, most likely the I+ ion, is generated. The use of the I/II mechanistic probe suggests the following description of the iodination reaction: electrophilic substitution at the aromatic nucleus, with a transition state properly represented in terms of a σ-complex. The radical cation of II also forms when the iodination is carried out by means of oxidizing agents, but it is solely responsible for the formation of side-chain substitution products and is not involved in the nuclear substitution process.
