摘要

Electrochemical reduction of pentafluoropyridine and other polyhalopyridines gives bipyridyl derivatives etc. and it is inferred from the structures of the products that, in the intermediate radical-anion, charge-and spin-density is concentrated at the 1-and 4-positions. This is further supported by measurement of Ep1 2 values. Trapping experiments with hydroquinone and carbon dioxide are described.
