This report describes the design, synthesis, solubility, and electrochemistry of a series of tris-bipyridine chromium complexes that exhibit up to six reversible redox couples as well as solubilities approaching 1 M in acetonitrile. We have systematically modified both the ligand structure and the oxidation state of these complexes to gain insights into the factors that impact solubility and electrochemistry. The results provide a set of structure-solubility-electrochemistry relationships to guide the future development of electrolytes for nonaqueous flow batteries. In addition, we have identified a promising candidate from the series of chromium complexes for further electrochemical and battery assessment.
Facile synthesis of polypyridine esters: A route to functionalized aldehydes

A wide range of ester-substituted oligopyridines, based on pyridine, 1,8-naphthyridine, 1,10-phenanthroline, 2,2'-bipyridine, and 2,2':6',6-terpyridine units, has been synthesized and fully characterized. The principal reaction involves the palladium(0)-catalyzed carboalkoxylation of the bromo-, chloro- or triflate-substituted pyridine unit with carbon monoxide in the presence of a primary alcohol as nucleophile and a tertiary amine as base. Monofunctionalization of disubstituted compounds is realized by reaction in ethanol under mild conditions (70 °C, 1 atm CO). Stepwise reduction of selected esters with sodium borohydride, followed by Swern oxidation, affords the corresponding carbaldehydes in good yield. Several products are reported for the first time. The synthetic methods reported herein represent a valuable approach to the large-scale preparation of ester-functionalized oligopyridines that can be subsequently transformed to the corresponding alcohols or acids. These procedures also provide a practical methodology to the rational design of ligands bearing different kinds of functionalities.
