This invention relates to novel alpha-substituted α,β-unsaturated E- or Z-aldehydes, or isomer mixture thereof, of the formula
in which R
1
and R
2
may be identical or different and are each H or a hydrocarbon, in which the hydrocarbon may have one or more heteroatoms and R
3
and R
4
may be identical or different and are each a hydrocarbon, in which the hydrocarbon may have one or more heteroatoms, and R
