Rechargeable cells with a sulfur cathode, a lithium anode and a nonaqueous electrolyte operating at ambient temperature have been extensively studied as a possible application of sulfur combined with nonaqueous solvent. However, the behavior of the chemical species formed by the reduction of sulfur

β¦ Synopsis
Although desulfurization can be effected by a variety of chemical means 1'2 (see ref. 1 for a recent summary), anodic elimination of sulfur is a novel process 3. Sulfoxides and sulfones are the usual anodic oxidation products of sulfides in nonaqueous 4'5 and aqueous 6'7 solutions. Under rigorously nonaqueous conditions, Cottrell and Mann s found sulfonium ions produced in the oxidation of simple aliphatic sulfides. This communication reports on the electrochemical oxidation of two sulfur heterocycles (( 1) and (3)below)in which the oxidative elimination of sulfur is a major anodic pathway. Disulfide coupling products, which were expected by analogy to the well-studied cysteine-cysteine system 9 and others 1Β°'11, were not major products of the preparative scale electrolyses.

One of the defining physicochemical features of DNA in aqueous solution is its ability to maintain a double-helical structure and for this structure to undergo a cooperative, heat-induced denaturation (melting). Herein we show that a 21-mer synthetic DNA can form and maintain such a duplex structure
