Unsaturated aldehydes are prepared by mixing propargyl alcohol, a catalyst and a conjugated diolefin and heating the mixture for a time and at a temperature sufficient to form an unsaturated aldehyde. The diolefin may be 2-methylpentadiene, 2-(5,5- dimethyl- 5-hydroxy-pentyl)-1,3-butadiene or myrcene. The catalyst may be inorganic, organic, organometallic or mixtures thereof.
