3-Carboxyphenylboronic acid Chemical Properties,Usage,Production

Chemical Properties

3-Carboxyphenylboronic acid is off-white crystalline powder

Uses

suzuki reaction

Uses

3-Carboxyphenylboronic acid can be used as a substrate in the preparation of:

  • Biaryl derivatives by reacting with bromoaniline through the Suzuki-Miyaura coupling reaction.
  • Boronic acid-functionalized block copolymer.
  • 1H-Imidazo[1,2-a]quinoxaline derivatives.

Uses

3-Carboxyphenylboronic acid is used in Suzuki coupling chemistry.1,2,3

Synthesis

150255-96-2

25487-66-5

1. Synthesis of 3-carboxyphenylboronic acid: 10 g (68 mmol) of 3-cyanophenylboronic acid was suspended in 40 mL of ethylene glycol with 15.26 g (272 mmol, 4 eq.) of potassium hydroxide powder, heated to 175 °C and maintained for 3 hours. After completion of the reaction, the reaction mixture was cooled and diluted with 60 mL of water. The pH was adjusted to 2-3 with 32% hydrochloric acid solution, colorless crystalline 3-carboxyphenylboronic acid was precipitated and the product was separated by filtration. The resulting crystals were washed with water and dried under mild vacuum at 35 °C. The final product was 10.04 g in mass. The final product was 10.04 g (60.5 mmol, 89% yield).
