Abstract

Electrochemical studies in superbasic media with N-methylpyrrolidone and dimethylacetamide Electrochemical reactions were examined in dimethylformamide, dimethylacetamide and N-methylpyrrolidone which had been completely dried so that water was no longer electroactive. Electron exchange occurs normally over the whole activity range; however, the hydrogen electrode functions only in the acidic half of the pH range. It is therefore impossible to analyse acid-base reactions in superbasic media by this electrochemical method. The phenomena are analogous with those found in tetrahydrofuran and dimethoxyethane. The behaviour of the very weak acids fluorene, indene, phenylacetylene and triphenylmethane is discussed.
