4-(4-Nitrobenzyl)pyridine in Reaction with Diferrocenyl(methylthio)cyclopropenylium Iodide
Diferrocenyl(methylthio)cyclopropenylium iodide reactswith nitro compounds as CH-acids in the presence of triethylamine toyield both products with retention of the three-carbon ring and ringopeningproducts. Thus, 4-(4-nitrobenzyl)pyridine affords 1,2-diferrocenyl-3,3-dimethylthio- and 1,2-diferrocen...

| Resumo: | Diferrocenyl(methylthio)cyclopropenylium iodide reactswith nitro compounds as CH-acids in the presence of triethylamine toyield both products with retention of the three-carbon ring and ringopeningproducts. 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-1,3-diene. Theirstructures were established based on data from 1H and 13C NMR spectroscopyand X-ray diffraction analysis. The mechanistic aspects ofthese reactions are discussed. |
