4-Formylphenyl boronic acid crystallizes in colorless needles [1] or is obtained as an odorless, whitish powder, which dissolves little in cold but better in hot water. The compound is quite stable [3] and readily forms dimers and cyclic trimeric anhydrides, which complicate purification and tend to protodeboronize, a secondary reaction that occurs frequently in the Suzuki coupling, with ...
