Dibromophenols are a group of bromophenols consisting of one hydroxy group and two bromine atoms bonded to a benzene ring. There are six structural isomers , each with the molecular formula C 6 H 4 Br 2 O, which differ by arrangement of the substituents.
The molecule consists of a pair of monobrominated indolin-3-one rings linked by a carbon-carbon double bond. Dibromoindigo can also be produced enzymatically in vitro from the amino acid tryptophan. The sequence begins with bromination of the benzo ring followed by conversion to 6-bromoindole. Flavin-containing monooxygenase then couples two of ...
The 5-bromo-L-tryptophan can then undergo two separate reactions. One route involves a second bromination by AetF at position 7 to yield 5,7-dibromo-L-tryptophan. This molecule then goes on to react with AetD, an iron-dependent nitrile synthase, to form an indole-3-carbonitrile derivative.
Chemical structure of 2-bromophenol. A bromophenol is an organic compound consisting of hydroxyl groups and bromine atoms bonded to a benzene ring. They may be viewed as hydroxyl derivatives of bromobenzene, or as brominated derivatives of phenol.
The compound is based on the indole structure, but the 2-3 bond is saturated. By oxidation/dehydrogenation it can be converted to indole. [1] [2] Indoline can be produced from the reaction of indole, zinc and 85% phosphoric acid. [3] It was used to make Indocaine.
