摘要: Abstract The condensation of α-carbanion Fischer-type carbene complex with 2-thiomethyl-1,3-dithiolium salts 1 gave new heterocyclic organometallic carbenes 2 potentially precursors extended TTF. Reaction allylic carbanion 4 derived from (methoxypropenyl)pentacarbonyl afforded a mixture monoheterocyclic products 7 and diheterocyclic complexes 8 produced successive α γ attacks the cations.
