Reaction of Dilithiated Carboxylic Acids with Iodine: Evidence for the Formation of a Radical Anion Intermediate

The mechanism for oxidative dimerization of carboxylic acid dianions involves single electron transfer to iodine, producing an organic anion radical.Rearrangement of this species was observed with suitable substrates at a rate competitive with intermolecular reactions.The radical anion can dimerize or react with iodine.The iodide thus generated can be isolated (reaction with excess of iodine) or can participate in a polar SN2-type reaction sequence leading to dimeric products (reaction with 1/2 equiv of iodine).The interference by free amines (liberated during the metalation with lithium amides) is rationalized by the formation of a charge-transfer complex with iodine which decomposes, liberating protons.
