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 ]
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 ...

Phenyl radical group. In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø.
Mace is the brand name of an early type of aerosol self-defense spray invented by Alan Lee Litman in the 1960s. The first commercial product of its type, Litman's design packaged phenacyl chloride (CN) tear gas dissolved in hydrocarbon solvents into a small aerosol spray can, [1] usable in many environments and strong enough to act as a deterrent and incapacitant when sprayed in the face.
Illustrative is the preparation of isopropyl thiocyanate by treatment of isopropyl bromide with sodium thiocyanate in boiling ethanol. [5] The main complication with this route is the competing formation of alkyisothiocyanates. "SN1-type" substrates (e.g., benzyl halides) tend to give the isothiocyanate derivatives.
Phenacyl chloride, also commonly known as chloroacetophenone, is a substituted acetophenone. It is a useful building block in organic chemistry . Apart from that, it has been historically used as a riot control agent , where it is designated CN . [ 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 synthesis. It is, for example, the precursor to hydroxyacetone by reaction with aqueous sodium hydroxide. [6]
