  2. Phenylboronic acid - Wikipedia

    en.wikipedia.org/wiki/Phenylboronic_acid

    Phenylboronic acid or benzeneboronic acid, abbreviated as PhB(OH) 2 where Ph is the phenyl group C 6 H 5 - and B(OH) 2 is a boronic acid containing a phenyl substituent and two hydroxyl groups attached to boron. Phenylboronic acid is a white powder and is commonly used in organic synthesis.

    en.wikipedia.org/wiki/Boronic_acid

    The general structure of a boronic acid, where R is a substituent. A boronic acid is an organic compound related to boric acid (B(OH) 3) in which one of the three hydroxyl groups (−OH) is replaced by an alkyl or aryl group (represented by R in the general formula R−B(OH) 2). [1]

  4. Protodeboronation - Wikipedia

    en.wikipedia.org/wiki/Protodeboronation

    Basic heteroaromatic boronic acids (boronic acids that contain a basic nitrogen atom, such as 2-pyridine boronic acid) display additional protodeboronation mechanisms. [4] A key finding shows the speciation of basic heteroaromatic boronic acids to be analogous to that of simple amino acids , with zwitterionic species forming under neutral pH ...

  5. 4-Formylphenylboronic acid - Wikipedia

    en.wikipedia.org/wiki/4-Formylphenylboronic_acid

    4-Formylphenyl boronic acid crystallizes in colorless needles [2] or is obtained as an odorless, whitish powder, which dissolves little in cold but better in hot water. The compound is quite stable [4] 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 ...

  6. Borinic acid - Wikipedia

    en.wikipedia.org/wiki/Borinic_acid

    Borinic acid, also known as boronous acid, is an oxyacid of boron with formula H 2 BOH. Borinate is the associated anion of borinic acid with formula H 2 BO −; however, being a Lewis acid, the form in basic solution is H 2 B(OH) − 2. Borinic acid can be formed as the first step in the hydrolysis of diborane: [1] BH 3 + H 2 O → H 2 BOH + H 2
