Cations are crucial components in emerging functional polyelectrolytes for a myriad of applications. Rapid development in this area necessitates the exploration of new cations with advanced properties. Herein we describe a combination of computational and experimental design of cobaltocene metallo-cations that have distinct electronic and redox properties. One of the direct outcomes on the first synthesis of a complete set of cation derivatives is to discover highly stable cations, which are further integrated to construct metallo-polyelectrolytes as anion-exchange membranes in solid-state alkaline fuel cells. The device performance of these polyelectrolytes under highly basic and oxidative environments is competitive with many organo-polyelectrolytes.

UV-irradiation of assembled urea-tethered triphenylamine dimers affords persistent and regenerable radicals whereas the compound quickly degrades in solution.

An atom economic, electrochemical, concurrent synthesis of amides and benzoic esters.

A direct electrochemical synthesis of 1H-substituted benzimidazoles is described. Benzimidazole is a commonly used nitrogen heterocycle in U.S. FDA approved drugs; therefore, a direct and sustainable approach that limits chemical waste for the synthesis of substituted benzimidazoles is appealing. The electrosynthetic approach described within is able to synthesize a variety of 1H-substitubed benzimidazoles while concurrently producing H 2 , without a transition-metal catalyst or added bases. Furthermore, the procedure works efficiently with only simple carbon electrodes, thus avoiding commonly employed platinum and gold electrodes. This electrochemical procedure also exhibited good functional group tolerance. Desired products were achieved with up to 88% yield, illustrating the range and possible sustainability of this approach.
