Abstract
The Raman, UV-visible, electron spin resonance spectroscopic, and spectroelectrochemical (SEC) behavior of tetrachloro-<i>p</i>-benzoquinone (chloranil) in molten aluminum chloride/sodium chloride mixtures has been examined. The results support previous findings suggesting that the chloranil is complexed by AlCl<sub>3</sub>or Al<sub>2</sub>Cl<sub>7</sub>,- in acidic melts [>50 mole percent (m/o) AlCl<sub>3</sub>], while in basic melts (<50 m/o AlCl<sub>3</sub>) the chloranil remains uncomplexed. The results further support the previously proposed stepwise one-electron reductions in the acidic melt to produce the radical anion and the dianion. The present work, however, reveals that chloranil is also reduced through two closely spaced one-electron reductions in the basic melt.
