## Abstract The readily available alkyl dicyanoacetates 1 reacted with the 1,3‐dipolar reagents arenecarbonitrile oxides 2′ and arenecarbonitrile imines 5′ to afford 1,2,4‐oxadiazol and 1,2,4‐triazol derivatives. The arenecarbonitrile oxides 2′ with electron‐donating groups on the arene ring gave p
