Persulfides are receiving increased attention due to their links to hydrogen sulfide (H2S) and hydrogen polysulfide (H2Sn). Their close analogues selenyl sulfides (RSeSHs), however, have limited literature precedent, and their reactivity and possible role in biology are largely unknown. Here, we devised an acyl selenyl sulfide template to study RSeSH chemistry. Their stability and reactivity toward amines/thiols were studied. These compounds can produce H2S or H2S2 under different conditions, suggesting that RSeSHs are possible intermediates.
Generation of reactive oxygen species by a persulfide (BnSSH)

Hydropersulfides (RSxSH) have been implicated as important intermediates in the cell-killing action of the anticancer natural products leinamycin and varacin. It has been suggested that persulfides can mediate the conversion of molecular oxygen to reactive oxygen species (O2 .-, H2O2, and HO.). Here, experiments with synthetic benzyl hydrodisulfide (BnSSH) provide direct evidence that persulfides readily decompose to produce reactive oxygen species under physiologically relevant conditions.
