The 1,3-cycloaddition of aryl azides to the olefinic bonds of 4- and 2-vinylpyridines has been found to yield pyridyl substituted aziridines as the main reaction products with only smaller amounts of the normally expected 1-aryl-5-pyridyl-1,2,3-triazolines. Theoretical and experimental evidence are
