One-pot process for preparation ferrocenylethene derivatives by solvent-free Wittig Reaction of ferrocenecarboxaldehyde, alcohol, triphenylphosphonium bromide, and NaOH without the synthesis of phosphorus ylides was reported. The ferrocenylethene products obtained had an 80% yield with NaOH as the base at room temperature for 30 to 90 minutes.
