Summary:
The complexes of iodine with linear alkyl (C1, C8, C10 , C12 , C14 and C16) dimethylamine oxides have been studied in the solvents heptane, dichloromethane, and water. In the solvents heptane and dichloromethane and in aqueous surfactant micelles, alkyldimethylamine oxides react with iodine to form donor-acceptor complexes. Trimethylamine oxide is not soluble in heptane and does not form micelles in water so no complexes were fanned in these systems. In heptane and in dichloromethane the molecular complex ionizes to an "inner" complex in the presence of unassociated amine oxide. The effect of the surface activity is to reduce the concentration of free amine oxide and suppress this ionization. In the case of trimethylamine oxide in dichloromethane forming the dihydrate suppresses inner complex formation. In aqueous micelles the inner complex hydrolyzes to the protonated amine oxide, iodide ion, and hypoiodous acid which appears to oxidize water to molecular oxygen in the presence of the amine oxide micelles. Excess iodine complexes with iodide ion yielding triiodide ion which forms an undissociated ion pair with the micellar protonated amine oxide.
