To prepare 2 - (4,4,5,5-tetramethyl-1,3,2-dioxaborhexaborane-2-yl), there are many methods for synthesis, each with its own ingenuity.
First, halogenated aromatics and diphenol borate can be used as raw materials and obtained by boration under palladium catalysis. Among halogenated aromatics, halogen atoms have different activities, chlorine activity is slightly inferior, while bromine and iodine are more active, and the reaction conditions are also different. Suitable bases, such as potassium carbonate, sodium carbonate, etc., need to be selected to promote the reaction. In this process, the choice of solvent is also crucial. Common organic solvents such as toluene and dioxane can provide a good environment for the reaction, so that the reactants can be fully contacted and the reaction rate can be accelerated.
Second, boric acid and corresponding alcohols are used as starting materials. Under the action of acid catalysis, borate esters are formed into intermediates. After methylation and other steps, tetramethyl groups are introduced to build the target structure. The acid catalyst can be selected from concentrated sulfuric acid, p-toluenesulfonic acid, etc. The dosage and reaction temperature need to be carefully adjusted to prevent overreaction or side reactions. Methylation reagents commonly used in methylation steps, such as iodomethane and dimethyl sulfate, should be selected according to the comprehensive consideration of reaction conditions and safety.
Third, use the Grignard reagent method. Prepare the Grignard reagent containing boron first, and then react with the appropriate halogenate or carbonyl compound to gradually build the target molecular structure. When preparing Grignard reagents, the ratio of halogenated hydrocarbons to magnesium and the choice of reaction solvents (such as anhydrous ethyl ether and tetrahydrofuran) have a profound impact on the reaction. Subsequent reactions with halogenates or carbonyl compounds also need to be carefully controlled to obtain higher yields.
All synthesis methods have their own advantages and disadvantages. They need to be selected according to actual needs, such as the availability of raw materials, the difficulty of reaction conditions, and the purity of the product.
