p-Dimethylaminobenzophenone is related to Michler's ketone, but with only one amine. [5] Auramine O, a dye, is a salt of the iminium cation [(CH 3) 2 NC 6 H 4] 2 CNH 2 +.Michler's thione, [(CH 3) 2 NC 6 H 4] 2 CS, is prepared by treatment of Michler's ketone with hydrogen sulfide in the presence of acid or sulfideing auramine O. [6] Hydride reduction of Michler's ketone gives 4,4'-bis ...

Methyl 4-bromophenylacetate is made from 4-bromophenylacetic acid by Fischer esterification, refluxing it with methanol acidified with sulfuric acid. [3] An ethyl ester can be made in an analogous way using ethanol instead of methanol. [4] A hydrazone derivative, 2-(4-bromophenyl)acetohydrazide, is made by refluxing the methyl ester with ...
Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
This encouraged workers at Rhône-Poulenc to expand their own research into molecules with the same mode of action as these 4-hydroxyphenylpyruvate dioxygenase inhibitors. In doing so, they found that isoxaflutole had commercial potential as a propesticide of a biologically active diketonitrile that it was converted into within plants. [ 4 ]
4-Bromoaniline is a compound where an aniline molecule is substituted with a bromine atom on the para position. Commercially available, this compound may be used as a building block, e.g. in the preparation of monobrominated biphenyl via the Gomberg-Bachmann reaction .
Tris(4-bromophenyl)ammoniumyl hexachloroantimonate is the organic compound with the formula [(4-BrC 6 H 4) 3 N]SbCl 6. [1] Commonly known as magic blue, it is the hexachloroantimonate salt of an amine radical cation. It is a blue solid that reacts with many solvents but is soluble in acetonitrile.
Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
