dear all
 i am trying to synthesise ferrocene monoaldehyde by the vilsmeier haack
reaction.
initially i tried DMF + POCl3 but the rxn gave poor yields
so i used n methyl formanilide instead of DMF; the rxn looks like going
well but i am unable seaparate the product which should be crystalline.
instead i am getting a viscous liquid which shows 2 or 3 other spots on
TLC and which i am unable to separate by column chromatography
can somebody give me suggestion or is there an easy methd to get the aldehyde

desparately yours
santosh
