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]
Structure of a compound containing a phenacyl group. 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 ...
In organic chemistry, an α-halo ketone is a functional group consisting of a ketone group or more generally a carbonyl group with an α-halogen substituent. α-Halo ketones are alkylating agents. Prominent α-halo ketones include phenacyl bromide and chloroacetone .
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. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...
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.
It is usually formed as an unwanted product in burning processes of organic materials or as a side product in organic synthesis. TCDD is the most potent compound ( congener ) of its series (polychlorinated dibenzodioxins , known as PCDDs or simply dioxins ) and became known as a contaminant in Agent Orange , an herbicide used in the Vietnam War ...
In the laboratory, phenylacetylene can be prepared by elimination of hydrogen bromide from styrene dibromide using sodium amide in ammonia: [3]. It can also be prepared by the elimination of hydrogen bromide from bromostyrene using molten potassium hydroxide. [4]
Organic thiocyanates are organic compounds containing the functional group RSCN. the organic group is attached to sulfur: R−S−C≡N has a S–C single bond and a C≡N triple bond. [1] Organic thiocyanates are valued building blocks. They allow to access efficiently various sulfur containing functional groups and scaffolds. [2]
