Boronic acid, B-(2-methoxy-4-pyridinyl)- - Introduction

2-Methoxypyridne-4-boronic acid is an organic boron compound with the chemical formula C6H8BNO3. It has the form of a white to pale yellow crystalline solid.

2-Methoxypyridne-4-boronic acid is widely used in the field of organic synthesis. It is an important boronic acid reagent and can be used as one of the ligands in Suzuki-Miyaura cross-coupling reactions, reacting with organic halides or organic boronic esters to generate the corresponding coupling products. In addition, it can also be used as an intermediate of fine chemicals for the synthesis of drugs, dyes and other compounds.

The method of preparing 2-Methoxypyridne-4-boronic acid is usually carried out by methylation reaction. A common preparation method is to react 2-tolylpyridine with trimethylborane, and then react the resulting intermediate with boric acid to finally obtain the target product.

2-Methoxypyridne-4-boronic acid is relatively stable at room temperature, but avoid direct sunlight. It is a flammable substance and needs to be kept away from open flames and high temperatures. During the operation, attention should be paid to protective measures, such as wearing protective glasses and gloves. At the same time, avoid contact with strong oxidants and acidic substances during storage.
