## Abstract The 1,3‐dipoles 2,4,6‐trimethylbenzonitrile oxide and benzyl azide react with alkyldicyanamides (**1**) to give the 3,5‐disubstituted 1,2,4‐oxadiazoles **2** and the 1,5‐disubstituted tetrazole **4**, respectively, by (3 + 2)‐cycloaddition. The structure of 4 has been determined by a si
