Competition between base addition and electron transfer in unsaturated systems: the case of 3-methoxytropone
Abstract
Mixing of 3-methoxytropone with methanolic potassium methoxide in dimethyl sulphoxide leads to a σ-adduct which was observed by u.v. spectroscopy. Also observed was 3-methoxytropone radical anion by both u.v. and e.s.r. spectroscopy. The latter species was also electrolytically generated in both dimethylformamide and dimethyl sulphoxide.
