Reaction of the lithium dithiolene radical with the imidazolium salt [{(Me)CN(-Pr)}CH][Cl] (in a 1:1 molar ratio) gives the first stable naked anionic dithiolene radical , which, when coupled with hexasulfide, [{(Me)CN(-Pr)}CH][S] (), and N-heterocyclic silylene , unexpectedly results in synergic THF ring-opening via a radical mechanism.
锂二硫自由基与咪唑翁盐[{(Me)CN(-Pr)}CH][Cl](摩尔比为 1:1)反应生成首个稳定的裸露阴离子二硫自由基,该自由基与六硫化物[{(Me)CN(-Pr)}CH][S]()和 N-杂环硅烷反应,出人意料地通过自由基机制协同开环 THF。
