The invention belongs to the field of organic synthesis, and relates to a method for preparing a 4-substituted oxyphenol compound. The method comprising the following steps: condensing hydroquinone and a halogen compound in a polar aprotic solvent in a reducing agent and metal alkali system to obtain the 4-substituted oxyphenol compound; removing the solvent after the above reaction, adding a non-polar solvent, filtering, washing, and recovering the raw material hydroquinone; and washing the obtained filtrate through using water, extracting by using an alkaline solution, and adjusting the pH value of the obtained extract solution to obtain the 4-substituted oxyphenol compound. The method has the advantages of short route, simple operation, high selectivity, high yield, good atom economy, high product content, recovery convenience and recycling of the raw material, reduction of three wastes and the cost, and suitableness for industrial production.
