Abstract

Stable as a solid at −40°C, dithiatriselane 1 was formed in the reaction of Se2Cl2 with liquid H2S in CS2, in addition to other disproportionation products such as 2 and 3. Reactions in H2S2 provided sulfur-rich thiaselanes. The 1H and 77Se NMR spectra of the product mixtures could be interpreted unambiguously.
