Mixed Halobenzene
Halobenzenes are a group of aryl halides consisting of a benzene ring with halogen atoms as substituents. This includes these groups of halobenzenes: *Fluorobenzenes *Chlorobenzenes *Bromobenzenes *Iodobenzenes Halobenzene may also refer to any of the monosubstituted halobenzenes: *Fluorobenzene *Chlorobenzene *Bromobenzene *Iodobenzene *Astatobenzene Mixed halobenzenes Mixed halobenzenes contain two or more types of halogens bonded to the same benzene ring: *Chlorofluorobenzene *Bromofluorobenzene *Fluoroiodobenzene *Bromochlorobenzene *Chloroiodobenzene *Bromoiodobenzene List of halobenzene derivatives * Haloanilines ** Fluoroaniline ** Chloroaniline ** Bromoaniline ** Iodoaniline * Haloanisoles ** Fluoroanisole ** Chloroanisole ** Bromoanisole ** Iodoanisole * Halobenzaldehydes ** Fluorobenzaldehyde ** Chlorobenzaldehyde ** Bromobenzaldehyde ** Iodobenzaldehyde * Halobenzoic acids ** Fluorobenzoic acid (other), Fluorobenzoic acid ** Chlorobenzoic acid ** Bromobenzoic a ...

Aryl Halide
In organic chemistry, an aryl halide (also known as a haloarene) is an aromatic compound in which one or more hydrogen atoms directly bonded to an aromatic ring are replaced by a halide ion (such as fluorine F''−'', chlorine Cl−1,−3,−5, bromine Br−1, or iodine I−). Aryl halides are distinct from haloalkanes (alkyl halides) due to significant differences in their methods of preparation, chemical reactivity, and physical properties. The most common and important members of this class are aryl chlorides, but the group encompasses a wide range of derivatives with diverse applications in organic synthesis, pharmaceuticals, and materials science. Classification according to halide Aryl fluorides Aryl fluorides are used as synthetic intermediates, e.g. for the preparation of pharmaceuticals, pesticides, and liquid crystals. The conversion of diazonium salts is a well established route to aryl fluorides. Thus, anilines are precursors to aryl fluorides. In the classic Schieman ...

Bromoiodobenzene
1-Bromo-4-iodobenzene is a mixed aryl halide (aryl bromide and aryl iodide) with the formula BrC6H4I. Preparation In one laboratory route to 1-bromo-4-iodobenzene, 4-bromoaniline is treated with concentrated sulfuric acid and sodium nitrite to form the diazonium salt, which is then treated with potassium iodide to form 1-bromo-4-iodobenzene. Reactions Since aryl iodides are more reactive than aryl bromides in the Sonogashira coupling, the iodine end of 1-bromo-4-iodobenzene can be selectively coupled to a terminal acetylene while leaving the bromine end unreacted, by running the reaction at room temperature. For example, two equivalents of 1-bromo-4-iodobenzene can couple to trimethylsilylacetylene in a room temperature symmetrical Sonogashira coupling (with TMSA being deprotected to acetylene ''in-situ'') to form bis(4-bromophenyl)acetylene. : See also *Bromobenzene *Iodobenzene *Bromochlorobenzene Bromochlorobenzenes are mixed aryl halides (aryl chloride and aryl bromide) co ...

Bromobenzaldehyde
Bromobenzaldehydes are any of three organic compounds with the formula BrC6H4COH, consisting of a formyl group and a bromine atom attached to a central benzene ring. They can be considered as aryl bromide, brominated derivatives of benzaldehyde, or as aldehyde, formylated derivatives of bromobenzene. References {{reflist Bromobenzene derivatives Benzaldehydes ...

Fluorobenzaldehyde
Fluorobenzaldehyde is a group of three structural Isomer, constitutional isomers of Halogenation, fluorinated benzaldehyde. Properties The isomers differ in the location of the fluorine, but they have the same chemical formulas. Preparation The 4-fluorobenzaldehyde isomer can be produced by a halogen-exchange reaction with 4-chlorobenzaldehyde. Uses Fluorobenzaldehyde can be used as a synthetic intermediate because the fluorine can be replaced via Redox, oxidation reaction. Due to the aldehyde group, the fluorobenzaldehydes can be used to make a variety of schiff base compounds through a condensation reaction, some of which have antimicrobial properties.
