2,4,6-Tribromoaniline is a brominated derivative of aniline with the formula C 6 H 4 Br 3 N. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents.
Brominating aniline with elemental bromine gives 2,4,6-tribromoaniline. This is then diazotized, then reacted with ethanol to replace the diazonium group with hydrogen, forming 1,3,5-tribromobenzene. [3] It has also been prepared by these methods: [3] replacement of the amino group of 3,5-dibromoaniline with bromine
The bromoanilines form a group of three isomers where the bromine atom occupies the para, ortho or meta position on the aromatic ring. Bromoaniline isomers Arene substitution patterns. The three isomers are: 2-Bromoaniline (o-Bromoaniline) [1] 3-Bromoaniline (m-Bromoaniline) [2] 4-Bromoaniline (p-Bromoaniline) [3]
4-Bromoaniline is a compound where an aniline molecule is substituted with a bromine atom on the para position. Commercially available, this compound may be used as a building block, e.g. in the preparation of monobrominated biphenyl via the Gomberg-Bachmann reaction. [2]
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
PBr 3 is prepared by treating red phosphorus with bromine. An excess of phosphorus is used in order to prevent formation of PBr 5: [1] [2] P 4 + 6 Br 2 → 4 PBr 3. Because the reaction is highly exothermic, it is often conducted in the presence of a diluent such as PBr 3. Phosphorus tribromide is also generated in situ from red phosphorus and ...

Silver bromide (AgBr). Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2; extreme nuclear instability hampering chemical investigation before ...
