Spectroelectrochemical studies on the reduction of thionyl chloride
- Univ. of New Mexico, Albuquerque, NM (United States). Dept. of Chemistry
The electrochemical reduction of thionyl chloride in dimethyl sulfoxide and of the thionyl chloride-lithium tetrachloroaluminate system has been studied using spectroelectrochemical techniques. Results indicate that the reduction mechanism of SOCl[sub 2] in the LiAlCl[sub 4]-SOCl[sub 2] solution is essentially the same as that in DMSO. The key intermediate species in this reduction is shown to be SO[sup +[sm bullet]], which is produced upon reduction of SOCl[sub 2] by a one-electron transfer, followed by the dechloridation process. This species then undergoes a series of following reactions to produce the final reduction products, S and SO[sub 2], via other intermediates such as SO and S[sub 2]O. At very negative potentials, reduction products of S and SO[sub 2] are shown to be produced.
