Abstract

Reactions of Hg(II) salts with thioether carboxylic acids o-C ₆H₄[CH(SCH₂COOH)₂]₂ (1a) and PhCH(SCH₂COOH)₂ (3) in water were found to lead to the decomposition of these ligands with the formation of mercury(II) mercaptoacetate Hg(SCH₂COOH)₂ (2) and aldehydes o-C ₆H₄(CHO)₂ and PhCHO, respectively. A similar reaction was observed between Hg(NO₃)₂ and CH ₃(CH₂)₂CH(SCH₂COOH)₂ (4). The X-ray structure of Hg(SCH₂COOH)₂ (2) shows a linear -S-Hg-S- moiety. The mechanism of the formation of 2 in the reactions between Hg²⁺ and thioether carboxylic acids in water is discussed.
