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 products 3a–d resulting from addition on both CN groups of 1, and those with electron-withdrawing groups provided mono-adducts 4a–e (Scheme 1). Arylnitrile imines 5′ reacted
