“…Using the measured E 1/2 value of 1 as a guide, E pa = -0.45 V vs Fc in THF, we expected that N-bromosuccinimide E pc = -0.37 V vs Fc in CH 3 CN, 16 and iodine, E pc = -0.140 V vs Fc in CH 3 CN, 17 could serve as mild oxidants. Treatment of 1 or 1-(DMEDA) with 1 equiv of N-halosuccinimide reagents (NXS; X = Cl, Br, I) or 0.5 equiv of iodine proceeded smoothly to Ce IV products.…”

Tuning Reactivity and Electronic Properties through Ligand Reorganization within a Cerium Heterobimetallic Framework

Cerium compounds have played vital roles in organic, inorganic, and materials chemistry due to their reversible redox chemistry between trivalent and tetravalent oxidation states. However, attempts to rationally access molecular cerium complexes in both oxidation states have been frustrated by unpredictable reactivity in cerium(III) oxidation chemistry. Such oxidation reactions are limited by steric saturation at the metal ion, which can result in high energy activation barriers for electron transfer. An alternative approach has been realized using a rare earth/alkali metal/1,1'-BINOLate (REMB) heterobimetallic framework, which uses redox-inactive metals within the secondary coordination sphere to control ligand reorganization. The rational synthesis of functionalized cerium(IV) products and a mechanistic examination of the role of ligand reorganization in cerium(III) oxidation are presented.

The electrochemical oxidation of halides and reduction of halogens have been studied in sulfolane, an aprotic solvent. Stable trihalide ions X3-are formed. The formation constants K of these X3-ions have been determined by potentiometry as lo7.* (X = I), (X = Br), and lo3.' (X = C1) in a 0.1 M LiC10, medium. The values of the constants K have also been obtained in methanol, a hydroxylic solvent, lo4.' (X = I), (X = Br), and in mixtures of both solvents (X = I). The variations of solvation energies of X3-and X-ions from one solvent to the other were estimated by means of a ferrocene electrode.

“…Thus, the ionic bonding strength between bromine and EMI + is stronger than that of iodide. 52,53 In general, in organic solvent, bromide is easily solvated and shows higher reactivity. However, the behavior of bromide in ionic liquids is different.…”
