Borylation is a chemical reaction that introduces a boron atom into an organic molecule. This process typically involves the use of boron-containing reagents, such as boronic acids or boron trifluoride, and is often used to modify alkenes or alkynes. Borylation is valuable in organic synthesis because it allows for the creation of new carbon-boron bonds, which can be further transformed into other functional groups. The resulting boron-containing compounds can be utilized in various applications, including the synthesis of pharmaceuticals and materials. Borylation is also a key step in cross-coupling reactions, which are important in forming complex organic structures. Overall, borylation is a versatile tool in modern chemistry.
