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.
Benzothiazole, or more specifically 1,3-benzothiazole, is an aromatic heterocyclic compound with the chemical formula C 7 H 5 NS.It is colorless, slightly viscous liquid. Although the parent compound, benzothiazole is not widely used, many of its derivatives are found in commercial products or in
In organic chemistry, benzoyl (/ ˈ b ɛ n z oʊ ɪ l /, BENZ-oh-il) [1] is the functional group with the formula −COC 6 H 5 and structure −C(=O)−C 6 H 5. [2] [3] It can be viewed as benzaldehyde missing one hydrogen. The benzoyl group has a mass of 105 amu. The term "benzoyl" should not be confused with benzyl, which has the formula − ...
Organotrifluoroborates are tolerant of air and moisture [1] and are easy to handle and purify. [2] They are often used in organic synthesis as alternatives to boronic acids (RB(OH) 2 ), boronate esters (RB(OR′) 2 ), and organoboranes (R 3 B), particularly for Suzuki-Miyaura coupling .
Protodeboronation is a well-known undesired side reaction, and frequently associated with metal-catalysed coupling reactions that utilise boronic acids (see Suzuki reaction). [1] For a given boronic acid, the propensity to undergo protodeboronation is highly variable and dependent on various factors, such as the reaction conditions employed and ...
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 ...
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]
Benzisothiazolinone (BIT) is an organic compound with the formula C 6 H 4 SN(H)CO. A white solid, it is structurally related to isothiazole, and is part of a class of molecules called isothiazolinones. [2] BIT is widely used as a preservative and antimicrobial. [3]
