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.

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.

Construction of isoxazolone-fused phenanthridines <i>via</i> Rh-catalyzed cascade C–H activation/cyclization of 3-arylisoxazolones with cyclic 2-diazo-1,3-diketones
A Rh(III)-catalyzed cascade C–H activation/intramolecular cyclization of 3-aryl-5-isoxazolones with cyclic 2-diazo-1,3-diketones was described, leading to the formation of isoxazolo[2,3-f]phenanthridine skeletons. The protocol features the simultaneous one-potformation of two new C–C/C–N bonds and one heterocycle in moderate-to-good yields with good functional group compatibility. It is amenable to
