Whereas redox processes resulted from the reactions PhSe−/S8 or PhSe2Ph/S3˙−, mixed anions RSSey− (R = Ph, PhCH2; y = 1–3) were obtained by the slow addition of solid selenium to thiolate ions in N,N-dimethylacetamide. The RS− + n Se react

The reactivity of selenolate ions RSe− [R = Ph (1), PhCH2 (2)] towards solid selenium has been investigated by UV-visible spectrophotometry in N,N-dimethylacetamide. After the slow formation of RSe2−, further addition of Se yielded RSe3− and RS
