Phenacyl bromide is the organic compound with the formula C 6 H 5 C(O)CH 2 Br. This colourless solid is a powerful lachrymator as well as a useful precursor to other organic compounds. It is prepared by bromination of acetophenone: [2] C 6 H 5 C(O)CH 3 + Br 2 → C 6 H 5 C(O)CH 2 Br + HBr. The compound was first reported in 1871. [3]
In organic chemistry, a phenacyl group is an aromatic substituent that consists of a phenyl group attached to an acyl group. A molecule containing a phenacyl group has the formula RCH 2 (CO)C 6 H 5 and the structure shown to the right. Here, R denotes the remainder of the molecule; for instance, if R is Br, then the compound could be called ...
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 ...
Bromobenzene is an aryl bromide and the simplest of the bromobenzenes, consisting of a benzene ring substituted with one bromine atom. Its chemical formula is C 6 H 5 Br. It is a colourless liquid although older samples can appear yellow. It is a reagent in organic synthesis.
The reaction of an organic substrate with phosgene is called phosgenation. [9] Phosgenation of diols give carbonates (R = H, alkyl, aryl), which can be either linear or cyclic: n HO−CR 2 −X−CR 2 −OH + n COCl 2 → [−O−CR 2 −X−CR 2 −O−C(=O)−] n + 2n HCl. An example is the reaction of phosgene with bisphenol A to form ...
Phenethyl alcohol is prepared commercially via two routes. Most common is the Friedel-Crafts reaction between benzene and ethylene oxide in the presence of aluminium trichloride. C 6 H 6 + CH 2 CH 2 O + AlCl 3 → C 6 H 5 CH 2 CH 2 OAlCl 2 + HCl. The reaction affords the aluminium alkoxide that is subsequently hydrolyzed to the desired product.
Methyl bromoacetate is an alkylating agent.It has been used to alkylate phenol and amino groups. [4] [5] Moreover, it can be used to make vitamins and pharmaceutical drugs.It is commonly used as a reagent in chemical modification of histidine. [2]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
