ResumoAbstract Push‐pull alkenes with variable structure were investigated with respect to the influence of the different substituents at the central C,C double bond on the dynamic behaviour of this type of compound. 1 H and 13 C NMR spectroscopic investigations were carried out for ketene‐ S , S ‐, ‐ S , N ‐ and ‐ N , N ‐acetals. HMO calculations were employed to discuss the related π‐electron density distributions.
