If the temperature is too high, it may cause side reactions to occur, resulting in unnecessary impurities; if the proportion of reactants is inappropriate, the yield of the product will be affected.
Second, it can be started from the relevant iodoaromatic hydrocarbon derivatives by gradually introducing hydroxyl groups and p-toluenesulfonyloxy groups First, through a suitable substitution reaction, the hydroxyl group is introduced into the molecular structure, and then the p-toluenesulfonyl chloride and other reagents are used to connect the p-toluenesulfonyloxy group under suitable alkaline conditions to complete the preparation of the target product. This approach requires careful selection of reagents and conditions for each step of the reaction to ensure that the reaction proceeds in the expected direction, and the intermediate products of each step of the reaction must be properly separated and purified to avoid the accumulation of impurities affecting the quality of the final product.
Third, other iodine-containing compounds are also used as raw materials to construct the molecular structure of hydroxyl (p-toluenesulfonyloxy) iodobenzene through a series of chemical transformations. This process may involve complex organic synthesis steps, such as the formation and fracture of carbon-iodine bonds, the transformation of functional groups, etc. It is necessary to have a deep understanding and grasp of the reaction mechanism of organic synthesis in order to effectively control the reaction process and improve the purity and yield of the product. In short, the preparation of this compound requires comprehensive consideration of various factors, careful design of reaction routes and conditions, and the ideal preparation effect can be achieved.

Hydroxy (tosyloxy) iodobenzene, that is, hydroxy (p-toluenesulfonyloxy) iodobenzene, this substance is potentially dangerous, and the following safety precautions should be paid attention to when using it:
First, because of its certain toxicity and irritation, contact with vulnerable skin, eyes and respiratory tract. Therefore, it is necessary to wear appropriate protective equipment, such as laboratory clothes, gloves and goggles, to prevent skin contact and splashing into the eyes. The operation should be carried out in a well-ventilated fume hood to avoid inhalation of its dust or volatile gases.
Second, the substance is chemically active and oxidizing, and improper storage and use can easily cause danger. It should be kept away from reducing agents, flammable materials and combustible materials, and stored separately to prevent violent reactions or even explosions. Storage should be placed in a dry, cool and ventilated place, protected from heat and fire sources, and stored strictly according to the specified conditions to prevent deterioration or cause safety accidents.
