3-Hydroxybenzylbenzyldiacetoxyborane is a chemical substance. Its storage method is quite important. This substance should be placed in a cool and dry place, because the cool and dry environment can reduce the risk of deterioration due to changes in temperature and humidity. If it is placed in a high temperature and humid place, its chemical properties may become easy and its effect will not exist. And it needs to be protected from light. Light can also lead to chemical reactions and damage its activity. Therefore, it should be stored in an opaque container to block light from contacting the object. Furthermore, it should be stored away from fire sources and oxidants. Due to its chemical activity, it may react violently in case of fire or oxidizing agent, causing dangerous things. It should also be placed separately from other chemicals to prevent their interaction and disruption of their chemical properties. After taking it, the container must be sealed to prevent the entry of air and water vapor to ensure the stability of its properties. Only in this way can 3-hydroxybenzylbenzyldiacetoxyborane be stored for a certain period of time without losing its properties and ready for use.

The synthesis method of 3-hydroxybenzylbenzyldiacetoxyborane has the following methods: First, benzyl alcohol and boric acid are used as starting materials. First, place an appropriate amount of benzyl alcohol in a clean reactor, slowly add boric acid, and add an appropriate amount of catalyst, such as concentrated sulfuric acid or p-toluenesulfonic acid. Heat up to a certain temperature and maintain the reaction at this temperature. During the reaction, pay close attention to the reaction process, and monitor the reaction by thin-layer chromatography (TLC). After the reaction is completed, cool the reaction system, then add an appropriate amount of solvent, such as dichloromethane or ethyl ether, stir well, and wash with an appropriate amount of sodium bicarbonate solution to remove excess acid. After separation, the organic phase was dried with anhydrous sodium sulfate, filtered, and distilled under reduced pressure to remove the solvent to obtain the preliminary product. Further purification was carried out by column chromatography, and a suitable eluent, such as a mixture of petroleum ether and ethyl acetate, was selected to obtain a pure 3-hydroxybenzylbenzyldiacetoxyborane. Second, benzyl halide and 3-hydroxyborate were used as raw materials. In the reaction vessel, put an appropriate amount of 3-hydroxyborate, and then add benzyl halide, such as benzyl chloride or benzyl bromide. At the same time, add an appropriate amount of base, such as potassium carbonate or sodium carbonate, and a phase transfer catalyst, such as tetrabutylammonium bromide. At a suitable temperature, stir the reaction for a period of time. Also monitor the reaction progress with the help of TLC. When the reaction is reached, cool, dilute with water, and extract with an organic solvent, such as dichloromethane for multiple extractions. The organic phases are combined, dried with anhydrous magnesium sulfate, filtered, distilled and concentrated under reduced pressure, and then purified by column chromatography. According to the characteristics of the product, a suitable eluent ratio is prepared to obtain 3-hydroxybenzylbenzylbenzyldiacetoxyborane. Third, benzaldehyde derivatives are used as starting materials. The benzaldehyde derivatives are first reacted with sodium acetoxyborohydride in a suitable solvent, such as methanol or ethanol. The reaction needs to be started at low temperature, gradually raised to room temperature and stirred. After the reaction, an appropriate amount of acid solution, such as dilute hydrochloric acid, is added to adjust the pH value. Then extract with an organic solvent, collect the organic phase, dry and concentrate. The obtained product is then reacted with a benzylboronic acid derivative in the presence of a catalyst, which can be a palladium catalyst or the like. At a suitable temperature and reaction conditions, the reaction is stirred to monitor the reaction progress. After the reaction is completed, it is post-treated, such as extraction, drying and concentration, and finally purified by column chromatography to obtain the target product 3-hydroxybenzylbenzyldiacetoxyborane.
