184.5 °c (364.1 °f; 457.7 k) Benzyl bromide is an isomer, which has a bromine substituted for one of the hydrogens of toluene 's methyl group, and it is sometimes named α-bromotoluene. Preparation
Nitrobenzene is an aromatic nitro compound and the simplest of the nitrobenzenes, with the chemical formula C 6 H 5 NO 2. It is a water-insoluble pale yellow oil with an almond -like odor. It freezes to give greenish-yellow crystals.
Bromoform can be absorbed into the body by inhalation and through the skin. The substance is irritating to the respiratory tract, the eyes, and the skin, and may cause effects on the central nervous system and liver, resulting in impaired functions. Its LD 50 is 7.2 mmol/kg in mice, or 1.8 g/kg. The International Agency for Research on Cancer ...
4-Fluorobromobenzene is synthesized via bromination of fluorobenzene in the presence of a Lewis acid catalyst such as iron(III) bromide or aluminium tribromide. [2]4-Bromofluorobenzene is regarded by the Toxic Substances Control Act as a high production volume chemical, that is, a chemical that 1 million pounds (about 500 tonnes) per year is either produced in or imported to the United States.
4-Nitrochlorobenzene is the organic compound with the formula ClC 6 H 4 NO 2. It is a pale yellow solid. 4-Nitrochlorobenzene is a common intermediate in the production of a number of industrially useful compounds, including antioxidants commonly found in rubber. Other isomers with the formula ClC 6 H 4 NO 2 include 2-nitrochlorobenzene and 3 ...
Common names o-bromochlorobenzene ortho-bromochlorobenzene m-bromochlorobenzene meta-bromochlorobenzene p-bromochlorobenzene para-bromochlorobenzene Systematic name: 1-bromo-2-chlorobenzene 1-bromo-3-chlorobenzene 1-bromo-4-chlorobenzene Molecular formula: BrC 6 H 4 Cl Molar mass: 191.45 g/mol CAS number: 694-80-4: 108-37-2: 106-39-8 ...
It undergoes the reactions typical for nitrobenzene derivatives, e.g. hydrogenation gives p-toluidine. Oxidation of the methyl substituent of 4-nitrotoluene has been extensively investigated. Depending on the conditions, oxidation yields 4-nitrobenzaldehyde diacetate, [ 6 ] 4-nitrobenzenoic acid, [ 7 ] and 4,4'-dinitrobibenzyl. [ 8 ]
An example is the symmetrical Sonogashira coupling of two equivalents of 1-bromo-4-iodobenzene with trimethylsilylacetylene (with the trimethylsilyl group removed in-situ) to form bis(4-bromophenyl)acetylene. [21]
