Abstract : In aprotic solvents the electrochemical reduction of tetracyanoquinodimethane (TCNQ) and electrochemical reduction of tetracyanoquinodimethane (TCNQ) and tetracyanoethylene (TCNE) takes place in two distinct one-electron steps. A radical anion is formed in the first step, and at much more negative potentials a further electron-transfer takes place to form a dianion. The first reduction step of TCNE and both reduction steps of TCNQ are very fast. The radical anions and dianions are stable in aprotic and oxygen-free solutions, except that the dianions and neutral molecules can reproportionate to form two radical anions. In this note we report a study by cyclic voltammetry of the reductions of TCNQ and TCNE to their radical anions and dianions at platinum and glassy carbon electrodes in acetonitrile.
