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.
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 ...
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]
The tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group [1] (BOC group) is an acid-labile protecting group used in organic synthesis. The BOC group can be added to amines under aqueous conditions using di- tert -butyl dicarbonate in the presence of a base such as sodium hydroxide :
3,3’,4,4’-Benzophenone tetracarboxylic dianhydride (BTDA) is chemically, an aromatic organic acid dianhydride. It may be used to cure epoxy-based powder coatings. It has the CAS Registry Number of 2421-28-5 and a European Community number 219-348-1. It is REACH and TSCA registered. The formula is C 17 H 6 O 7 with a molecular weight of 322. ...
4-Aminobiphenyl (4-ABP) is an organic compound with the formula C 6 H 5 C 6 H 4 NH 2. It is an amine derivative of biphenyl . It is a colorless solid, although aged samples can appear colored. 4-Aminobiphenyl was commonly used in the past as a rubber antioxidant and an intermediate for dyes. [ 5 ]
Bisphenol A is difunctional and used to produce epoxy resin and polycarbonate. 4-tert-Butylphenol is monofunctional and so in polymer science terms, bisphenol A is a polymer chain extender but 4-tert-butylphenol is a chain stopper or sometimes called endcapper. It is thus use to control molecular weight by limiting chain growth.
The benzoyl functional group.. 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.
