Product Details
Description |
Dibenzofuran-4-boronic acid (DBFBA) is a boronic acid derivative that has been employed as a cross-coupling agent in the Suzuki coupling reaction. The Suzuki coupling reaction is a widely used method in organic synthesis for the formation of carbon-carbon bonds. Initially, DBFBA was reported to have low efficiency in the Suzuki coupling reaction. However, advances in the field, such as the use of methanol extraction and consideration of photophysical properties, have likely contributed to improvements in its application. |
