3‐Arylsydnone‐4‐carbonitrile oxides may undergo 1,3‐dipolar cycloadditions with alkenes to produce the corresponding 3‐aryl‐4‐(5‐substituted‐isoxazolin‐3‐yl)sydnones. The direct reaction of 3‐arylsydone‐4‐carbohydroximic acid chlorides with alkenes may also give the same products, and with higher yield.
