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. There are five basic types of bromophenols (mono- to pentabromophenol) and 19 different bromophenols in total when positional isomerism ...

In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−O H) bonded directly to an aromatic hydrocarbon group. [1] The simplest is phenol, C 6 H 5 OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the ...
4-Bromothiophenol can be synthesized via the reduction of 4-bromo-benzenesulfonyl chloride by red phosphorus and iodine in an acidic solution. [3] Hydrogenation of 4,4'-dibromodiphenyl disulfide also produces 4-bromothiophenol. [4]
In organic chemistry, brosyl (or para-bromophenylsulfonyl) group is a functional group with the chemical formula BrC 6 H 4 SO 2 and structure Br−C 6 H 4 −SO 2 −R. This group is usually introduced using the compound brosyl chloride, BrC 6 H 4 SO 2 Cl, which forms sulfonyl esters and amides of p-bromophenylsulfonic acid. The term brosylate ...
4-Bromophenylacetic acid may be prepared by the addition of a bromine atom to phenylacetic acid through electrophilic aromatic substitution.It was first prepared in the laboratory by treatment of phenylacetic acid with bromine and mercuric oxide; a mixture of the 2- and 4- isomers is made, and the 4- isomer is isolated by fractional crystallization.
(2-Bromophenyl)diphenylphosphine is a precursor to unsymmetrical diphosphines. Many widely used diphosphine ligands have the general formula Ar 2 P(CH 2) n PAr 2.These compounds can be prepared from the reaction of X(CH 2) n X (X=halogen) and MPPh 2 (M = alkali metal): [3]
