Bromination of 4-arenesulfonamidophenols and -1-naphthols and N-(arylsulfonyl)-1,4-benzo(naphtho)quinone 4-imines was written by Avdeenko, A. P.;Velichko, N. V.. And the article was included in Zhurnal Organicheskoi Khimii in 1992.Product Details of 1146-43-6 This article mentions the following:
2,3,6-Tribromo-N-arylsulfonyl-1,4-benzoquinon-4-imines are formed by bromination of 4-arenesulfonamidophenols and N-arylsulfonyl-1,4-benzoquinon-4-imines, but in the case of 4-arenesulfonamido-1-naphthols and N-arylsulfonyl-1,4-naphthoquinon-4-imines only 2-bromo-N-arylsulfonyl-1,4-naphthquinon-4-imines are formed. In the experiment, the researchers used many compounds, for example, N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide (cas: 1146-43-6Product Details of 1146-43-6).
N-(4-Hydroxyphenyl)-4-methylbenzenesulfonamide (cas: 1146-43-6) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Product Details of 1146-43-6
