Alkylation of [WS4]2– : synthesis and structural characterization of the ethylthiolatotrithiotungstate(VI) anion
Abstract
Reaction of [PPh4]2[WS4] with ethyl bromide yields the tetraphenylphosphomum salt of the title anion 1, for which an X-ray structure determination reveals no evidence for an intramolecular redox reaction, but concentrated solutions undergo rapid reactions leading to [W3S9]2– and Et2Sx(x= 1–3).
