Abstract

Polarographic investigation of a series of potassium O-alkylxanthates in acetone has shown that they undergo the following processes at a mercury electrode. 2Hg⁰+6ROCS₂2Hg(S₂COR)₃^-+4e. 2Hg^II(S₂COR)₃^-+Hg⁰2Hg^II(S₂COR)₂+2e (where R is an alkyl group). Analysis of the two waves corresponding to these processes shows qualitative agreement with theoretical predictions for such a mechanism, although the system is complicated by adsorption phenomena. The complex Hg^II(S₂COC₄H₉)₂ has actually been isolated, and strong evidence for the existence of Hg^II(S₂COR)₃^- complexes has been obtained. Behaviour in other media is briefly reported.
