WebNov 18, 2024 · Synthesis of Acrylamidophenylboronic Acid 3-APBA (5581.0 mg, 40.7 mmol) was added in a two-necked flask and dehydrated at 40°C under vacuum for 30 min. The reaction was protected by argon. 3-APBA was completely dissolved in 84 mL of distilled THF at 0°C ice water bath by stirring. WebMar 26, 2024 · At low pH, phenylboronic acid adopts an uncharged and trigonal planar configuration, and it may binds with cis-diols. However, this binding is unstable and easily hydrolyzed. When pH values are larger than the pKa, phenylboronic acid exists in a negative charged and tetrahedral state, which binds with diols tightly.
