  The present invention to a process for preparing 2-alkenals of the formula I in which R 1 is selected from hydrogen and C 1 -C 4 -alkyl; and R 2 is selected from hydrogen, C 1 -C 12 -alkyl, C 2 -C 12 -alkenyl, C 4 -C 8 -cycloalkyl and C 6 -C 10 -aryl, wherein C 1 -C 12 -alkyl and C 1 -C 12 -alkenyl may be substituted with C 5 -C 7 -cycloalkyl or C 5 -C 7 -cylcoalkenyl; comprising dehydrogenating an alkenol of the formula II, an alkenol of the formula III or a mixture thereof, wherein R 1 and R 2 are each as defined above, wherein the alkenol II, the alkenol III or a mixture thereof is brought into contact with a catalytic system comprising at least one ligand and a metal compound selected from ruthenium(II) compounds and iridium(I) compounds, and wherein the hydrogen formed during the dehydrogenation is removed from the reaction mixture by: v) reaction with a reoxidant selected from C 3 -C 12 -alkanones, C 4 -C 9 -cycoalkanones, benzaldehyde and mixtures thereof; and/or vi) purely physical means.
