This invention, which involves synthetic method of 5, 5- dimethyl-2, 4-adipaldehyde-0, 0-Boron difluoride, belongs to the field of organic synthesis. Synthetic method of 5, 5-dimethyl-2, 4-adipaldehyde-0, 0-Boron difluoride is to react pinacolone and boron trifluoride diethyl ether at low temperature, and then add aqueous alkaline solution in after treatment to extract product from ether, after that, separate fluid, condense organic phase and final product is obtained. Yield of this method is 2 to 3 times higher than that in literature, and apart from that, mild reaction condition, simple procedures, easy operation, and low cost make it easy for industrial production. The product can be used directly in next step reaction without any special purification.
这项涉及5,5-二甲基-2,4-己二醛-0,0-硼二氟化物的合成方法属于有机合成领域。5,5-二甲基-2,4-己二醛-0,0-硼二氟化物的合成方法是在低温下使二甲基二酮和三氟化硼乙醚反应,然后在处理后加入水性碱性溶液以从乙醚中提取产物,之后分离液体,浓缩有机相,得到最终产物。该方法的产率比文献中的高2到3倍,除此之外,温和的反应条件、简单的操作程序、易于操作和低成本使其易于工业生产。该产品可以直接用于下一步反应,无需任何特殊纯化。
