Abstract The isoquinoline-catalyzed synthesis of pretended 1 H-azirines from phenacyl bromides and N, N′-dialkylcarbodiimides was repeated. The products do not possess the structure of antiaromatic 1 H-azirines, but simple N-acyl-N, N′-dialkylureas were formed instead. This structural corrigendum was confirmed by the independent synthesis of the known ureas and comparison of their 1 H NMR and 13 C NMR spectroscopic data in the ...
