3‐Arylsydnone‐4‐carbonitrile oxides (2), which are generated in situ by thermal dehydrochlorination of the corresponding hydroximic acid chlorides (1), undergo 1,3‐dipolar cycloadditions with sydnone‐4‐carbonitriles (6) to give 3‐aryl‐4‐[5‐(3‐arylsydnonyl)‐1,2, 4‐oxadiazol‐3‐yl] sydnones (9). These nitrile oxides (2) also react with alkyl‐ and arylnitriles to give 1,3‐dipolar cycloaddition products.
