Abstract:Abstract. Diferrocenyl(methylthio)cyclopropenylium iodide reacts with nitro compounds as CH-acids in the presence of triethylamine to yield both products with retention of the three-carbon ring and ringopening products. Thus, 4-(4-nitrobenzyl)pyridine affords 1,2-diferrocenyl- 3,3-dimethylthio- and 1,2-diferrocenyl-3-[(4-nitrophenyl)(4-pyridyl)methylidene]cyclopropenes and acyclic compounds: 2,3-diferrocenyl-1,3,3-tris(methylthio)propene and 2,3- diferrocenyl-1-methylthio-4-(4-nitrophenyl)-4-(4-pyridyl)buta-1,… Show more
