Some ferrocene derivatives of acylhydrazones

The title organometallic compounds were synthesized by the condensation of formyl and acetyl ferrocene with cyanoacetyl, propionyl, butyryl,o-furoyl,o-thiofuroyl andm-pyridinecarboxy hydrazine in anhydrous ethanol under reflux. The IR,¹H NMR, MS, and Mössbauer spectra for these compounds were recorded and are discussed.
