The invention provides a method for compounding benzofuran derivatives by adding C-O bonds into olefin molecules through non-metallic Lewis acid catalysis. The method includes step 1, subjecting raw materials, namely phenol derivatives, to three-step reactions to obtain olefin serving as a reaction substrate; step 2, adding non-metallic Lewis acid and methylbenzene into the reaction substrate obtained in the step 1, and obtaining the benzofuran derivatives after reaction. The method has the advantages that the non-metallic Lewis acid is taken as a catalyst during reaction, so that pollution ofresidual metal catalysts to products is avoided, and troubles in post-treatment are omitted.
