A Stable Naked Dithiolene Radical Anion and Synergic THF Ring-Opening.

ABSTRACT: Reaction of the lithium dithiolene radical 2^• with the imidazolium salt [{(Me)CN(i-Pr)}₂CH]⁺[Cl]^- (in a 1:1 molar ratio) gives the first stable naked anionic dithiolene radical 3^•, which, when coupled with hexasulfide, [{(Me)CN(i-Pr)}₂CH]⁺₂[S₆]^2- (4), and N-heterocyclic silylene 5, unexpectedly results in synergic THF ring-opening via a radical mechanism.
