Abstract: The self-condensation of crotonaldehyde was studied in the presence of tripyridyl π-allyl iron chloride.The product was confirmed as 6-methyl 1,3-cyclohexadiene-1-carboxaldehyde by Gc-MS, IR and 1H NMR.It was suggested that the possible mechanism of the reaction might be the initial ligand exchange of crotonaldehyde with tripyridyl π-allyl iron chloride followed by addition and cyclization with another molecule of crotonaldehyde.The selectivity of reaction was increased greatly by orientation effect of ligand in the complex without side reaction.

Key words: Crotohaldehyde, Self-condensation, Tripyridyl, π-allyl, iron, chloride complex
