Bromobenzene is prepared by the action of bromine on benzene in the presence of Lewis acid catalysts such as aluminium chloride or ferric bromide. [3]Bromobenzene is used to introduce a phenyl group into other compounds.
The crystal structures of the THF complexes of the Reformatsky reagents tert-butyl bromozincacetate [25] and ethyl bromozincacetate [26] have been determined. Both form cyclic eight-membered dimers in the solid state, but differ in stereochemistry: the eight-membered ring in the ethyl derivative adopts a tub-shaped conformation and has cis bromo groups and cis THF ligands, whereas in the tert ...

Denatonium, usually available as denatonium benzoate (under trade names such as Denatrol, BITTERANT-b, BITTER+PLUS, Bitrex, Bitrix, and Aversion) and as denatonium saccharinate (BITTERANT-s), is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharinate.

Benzyl bromide is used in organic synthesis for the introduction of the benzyl groups when the less expensive benzyl chloride is insufficiently reactive. [6] [7] Benzylations are often achieved in the presence of catalytic amounts of sodium iodide, which generates the more reactive benzyl iodide in situ. [3]
Benzyl benzoate is an organic compound which is used as a medication and insect repellent. [1] As a medication it is used to treat scabies and lice . [ 2 ] For scabies either permethrin or malathion is typically preferred. [ 3 ]
(E)-Stilbene, commonly known as trans-stilbene, is an organic compound represented by the condensed structural formula C 6 H 5 CH=CHC 6 H 5.Classified as a diarylethene, it features a central ethylene moiety with one phenyl group substituent on each end of the carbon–carbon double bond.
Ponceau 4R (known by more than 100 synonyms, [1]: 460–461 including as C.I. 16255, [2] cochineal red A, [2] C.I. acid red 18, [2] brilliant scarlet 3R, [2] brilliant scarlet 4R, [2] new coccine, [1]: 460 ) is a synthetic colourant that may be used as a food colouring.
