A palladium catalyzed insert reaction of isocyanides to 3-arylisoxazol-5(4H)-ones for the construction of 4-aminomethylidene isoxazolone derivates is reported. In this transformation, only the C–H bond of the methylene group was involved while the remaining ring structure was retained. In general, this work provided a new protocol for the synthesis of 4-aminomethylidene isoxazolones.

A palladium catalyzed ringexpansionreaction 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.
