“…The preparative ER of allyl dimethyl sulfonium salts was also complicated by the subsequent slow chemical reactions resulting in organomercury intermediates that could not be detected under polarographic conditions. 193 Besides the duration of the studied process, the state of the mercury electrode surface often proved to be of fundamental importance for the OMC formation. For example, voltammograms of iodo-and bromobenzenes, 128 lysozyme, 243 glutathione, 244 thiadiazoline derivative of spiroadamantane 245,246 and several other compounds, recorded on fresh mercury surface, on the one hand, and during repeated scans, on the other hand, dramatically differed from one another, the latter demonstrating new cathodic and anodic peaks.…”
