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]
The Guerbet reaction, named after Marcel Guerbet (1861–1938), is an organic reaction that converts a primary alcohol into its β-alkylated dimer alcohol with loss of one equivalent of water. The process is of interest because it converts simple inexpensive feedstocks into more valuable products.
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.
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 ...
The combination of organocatalysis and photoredox methods provides a catalytic solution to this problem. [32] In this approach for the α-alkylation of aldehydes, [Ru(bipy) 3] 2+ reductively fragments an activated alkyl halide, such as bromomalonate or phenacyl bromide, which can then add to catalytically-generated enamine in an ...
The Appel reaction is an organic reaction that converts an alcohol into an alkyl chloride using triphenylphosphine and carbon tetrachloride. [1] The use of carbon tetrabromide or bromine as a halide source will yield alkyl bromides, whereas using carbon tetraiodide , methyl iodide or iodine gives alkyl iodides .
The alkylation between N-methyl-2-nitrobenzylamine [56222-08-3] (1) and phenacyl bromide (2) gives CID:15326127 (3). Catalytic hydrogenation over Raney Nickel reduces the nitro group to give CID:15113381 (4). The reduction of the ketone group with sodium borohydride to alcohol gives [65514-97-8] (5).
It was used in World War I as a chemical weapon, called BA by British and B-Stoff by Germans.Due to its toxicity, it is not used as a riot control agent anymore. Bromoacetone is a versatile reagent in organic
