Bromination of acetanilide post lab questions
Bromination of benzaldehyde 16 at 0°C resulted in 2-bromo-5-hydroxybenzaldehyde 17. Reductive alkylation of benzaldehyde 17 with piperazine 18 gave intermediate 19, which, upon subsequent arylation with various boronic acids following the Suzuki coupling protocol, led to benzaldehyde 20. Water samples were collected in triplicates at six sites, four times in the last 12 months, in the Ouleout Creek watershed. At each site, field parameters such as dissolved oxygen, electrical conductivity, pH, temperature, and turbidity were recorded. Dissolved silica content was measured using a colorimetric method. c) Special reaction of phenols: Bromination, Kolbe-Schmidt reaction, Riemer-Tiemann reaction, Fries rearrangement, azocoupling, Pinacol-Pinacolone rearrangement.

May 13, 2010 · Since bromination of acetanilide is an electrophilic aromatic substitution, bromination would occur where you have the electrons. However, due to the bulkiness of the acetamido group, you could only have the bromination on the para-position hence you expect only the monobrominated product, p-bromoacetanilide. Aucune catégorie; Telechargé par Hichem Kesraoui Dictionnaire Scientifique Anglais-Francais 3e Ed Bromination of Acetanilide So in my organic chem lab we mixed acetic acid, NaClO, and NaBr to produce Br2 for an electrophilic aromatic substitution to occur. I'm very unsure what the mechanism is in producing Br2 and how do I calculate it from the mass of NaBr used, volume NaClO used, and volume acetic acid used? Amines constitute an important class of organic compounds derived by replacing one or more hydrogen atoms of ammonia molecule by alkyl/aryl group (s).

The acetanilide is now subjected to nitration by concentrated sulphuric acid and fuming nitric acid to obtain the two products, namely : para-nitro acetanilide (~ 90%) and ortho-nitro acetanilide (~ 10%).* Finally, the para-nitroaniline is obtained by carrying out the hydrolysis of the corresponding p-nitro acetanilide with 70% sulphuric acid.
