KEY WORDS ESR a-0x0-carbothioates a-0x0-carbodithioates Radical anions MO calculations ... Alkyl phenylglyoxalates (1) are easily transformed into persistent radical anions by electron transfer. Their ESR spectra clearly show an extensive spin delocalization over the whole molec~le.~ On preparative electro- reduction in protic3 as well as in aprotic4 media, 1 is reduced at its keto rather than its ester group. Reduction of methyl 1,l-dithiophenylglyoxalate (4a), ...
