Dilithio-2,5-dimethyl-2,4-hexadiene (4a) rearranges to the cross-conjugated 2,5-dimethylhexadienediyl dianion 11a. A mechanistic investigation proves the intermolecularity of this rearrangement, which is also observed when starting from 4b. The 3-lithio-2,5-dimethylhexadienyl anion 10a with
## The reaction of tetrachlorocyclopropene (1) with arenethiols (2a-e), followed by treatment with perchloric acid, gave tris(arylthio)cyclopropenylium perchlorates (3a-c and e), 1,1,2,3,3-pentakis(arylthio)-1-propenes (4a-d), and 2,3,3tris(arylthio)propenals (5a-d). The structures of tris(phenylth
