## Abstract The 1,3‐dipolar addition reaction of acrylonitrile to the betaine 1‐phenyl or methyl‐3‐oxidopyridinium is not so highly regioselective as generally assumed. New regioisomers are isolated. Their structures are proven by mass spectroscopy and proton‐and carbon‐NMR spectroscopy. Some 3,4di
C NMR spectra of 40 substituted acetals, carbonates, ortho ethers, 1,3-dioxocycloalkanes, 1,3-oxothiolanes and 1,3-0xazolidines were studied. The chemical shift of the C-a carbon atom was found to depend both on the number ( K ) and type of the hetero substituents at C-a. The effect of oxygen, nitro
