This article reports the reactions of salts of 4‐ureylmethylpyridinium and 4‐ethoxycarbonylaminomethylpyridinium with carbonylic compounds, performed with the aim of obtaining newvinylpyridiniumsalts. These reactions can lead to the formation of both condensation and dimerization products. The type of products formed is conditioned by the nature of the salts and carbonyl groups involved. The interest
