Reduction of maleate and fumarate by the CO2.- anion radical

The radical anion CO2.- reacts with fumarate and maleate at pH 5.3 mainly via electron transfer. The final products are a mixture of (-O2CCH2-)2, trans-( -O2CCH)2 and products with higher molecular weight. At higher pHs, the yield of fumarate and succinate decreases. The results suggest that though the radical anions formed by the reduction of fumarate and maleate have different structures, the final products are probably the same.

Novel Electrocatalytic Procedure for the Oxidation of Alcohols, Aldehydes, Cyclic Ketones, and C-H Bonds Adjacent to Olefinic or Aromatic Groups

A novel electrocatalytic procedure is described for the oxidation of primary and secondary alcohols, cyclic ketones, and C-H bonds adjacent to aromatic or olefinic groups.The procedure involves the use of the RuIVoxidant 2+ (trpy is 2,2',2''-terpyridine; bpy is 2,2'-bipyridine) in water at pH 6.8 or in dimethyl sulfone-water mixtures and is based on a electrochemical "shuttle" mechanism in which the RuIV complex is regenerated by electrochemical oxidation of II(trpy)(bpy)(H2O)>2+.
