The method of preparing (hydroxy (p-toluenesulfonyloxy) iodobenzene) benzene has been around for a long time. The first method is to start with iodobenzene, meet with m-chloroperoxybenzoic acid in an appropriate agent, and oxidize it at a controlled temperature to form iodobenzene. Then, iodobenzene and p-toluenesulfonic acid dance together in a suitable environment to obtain (hydroxy (p-toluenesulfonyloxy) iodobenzene) benzene. In this way, attention should be paid to the purity and temperature of the agent to prevent side reactions from hindering its production.
The two methods, based on benzene iodoyl dichloride, are first combined with water to make chlorine easy to become hydroxyl groups to obtain hydroxy iodobenzene. After that, the hydroxyiodobenzene and p-toluenesulfonyl chloride are combined in the state of alkali storage, and the alkali can help the reaction to go forward, binding the acid to produce (hydroxyl (p-toluenesulfonyloxy) iodine) benzene. In this way, the amount of alkali and the time of reaction are all important, and the yield is difficult to be high if the amount is not suitable and the time is not right.
Another method is to use iodobenzene and mercury acetate as the first, to produce iodobenzylmercury acetate. After hydrogen peroxide, it is then combined with p-toluenesulfonate, and it is cleverly turned, and it is also what you want. However, mercury is toxic, so when operating, protective measures must be taken, and the reason for the aftermath should be careful to avoid pollution and harm the
All kinds of preparation methods have their own advantages and disadvantages. The first method is simple and the oxygen agent is expensive; the second step is complex and the raw material is common; the third method is dangerous and clever. When choosing a method, when it is broken according to the situation, use it in quantity to obtain good results.
