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
由于过硫化物与硫化氢(H 2 S)和多硫化氢(H 2 S n)的联系,因此受到越来越多的关注。然而,它们的紧密类似物硒烯硫化物(RSeSHs)的文献报道有限,而且它们的反应性和在生物学中的可能作用在很大程度上尚不清楚。在这里,我们设计了一个酰基硒基硫醚模板来研究RSeSH化学。研究了它们对胺/硫醇的稳定性和反应性。这些化合物可在不同条件下产生H 2 S或H 2 S 2,表明RSeSH是可能的中间体。
