crystalline solid

Ferrocenecarboxaldehyde, is used to prepare chiral ferrocene aziridinylmethanols for selective azomethine ylide cycloaddtion. It is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals.

core: iron
reagent type: catalyst

It forms red crystals from heptane/CH2Cl2, EtOH or pet ether and sublimes at 70o/1mm. The cyanohydrin has m 104o (from *C6H6/EtOH). The semicarbazone has m 217-219o(dec) after recrystallisation from aqueous EtOH. The oxime provides two isomers from pet ether viz m 96-99o and m 155o. The O-acetyloxime has m 80-81o after recrystallisation from hexane [Lindsay & Hauser J Org Chem 22 355 1957]. The 2,4-dinitrophenylhydrazone has m 248o(dec). [Beilstein 16 IV 1798, Graham et al. J Am Chem Soc 79 3416 1957, Broadhead et al. J Chem Soc 650 1958.]
