## 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
