A palladium catalyzed ring expansion reaction of isoxazolones with isocyanides was disclosed. In the reaction, a cascade process involving ring‐opening/cyclization was suggested. The reaction features high atomic economy due to no elimination of CO₂ occurred. Moreover, products obtained demonstrate aggregation‐induced emission properties with relatively high solid‐state emission efficiencies.
