This application provides a method for preparing 1,2-benzisoxazole derivatives. This method is the first to develop a C-H activation strategy for generating 1,2-benzisoxazole using N-phenoxyamide as a substrate and acetic halide as a coupling agent under rhodium(III) catalysis. Under inert solvent conditions, and with the combined action of a transition metal catalyst and an oxidant, the acetic halide undergoes ortho-C-H bond alkynylation under the guidance of N-phenoxyamide, followed by intramolecular amine metallation of the carbon-carbon triple bond of the acetic acid. Finally, under the action of a base, deacylation and β-OH elimination occur, yielding a multifunctional 1,2-benzisoxazole derivative. Currently, the synthesis of 1,2-benzisoxazole remains challenging due to the scarcity of synthetic methods and limitations on specific substrates (multi-step synthesis, poor functional group compatibility, etc.). This reaction is expected to provide a new approach for the development and application of 1,2-benzisoxazole derivatives. It should be noted that the obtained product can also be applied to hole transport materials for perovskite solar cells. Specifically, a donor-acceptor structure is formed by combining a triphenylamine group with excellent hole transport capability and a benzoxazole group that can act as an electron acceptor. This molecule achieves a power conversion efficiency of 16.01%.
