2-Aminothiophenol can prepared in two steps, starting with the reaction of aniline with carbon disulfide followed by hydrolysis of the resulting mercaptobenzothiazole. [1] It can also obtained by zinc reduction of 2-nitrobenzene sulfonyl chloride .
Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2. Consisting of a phenyl group ( −C 6 H 5 ) attached to an amino group ( −NH 2 ), aniline is the simplest aromatic amine .
They are simultaneously an aniline and a phenol This page was last edited on 19 November 2024, at ...
Substrates containing two phenols (or an aniline and a phenol; see equation (8) below for a related example), undergo oxidative coupling in the presence of hypervalent iodine(III) reagents. Coupling of both the ortho and para positions is possible; however, the use of bulky silyl-protected phenols provides complete selectivity for para coupling ...
A nucleophilic aromatic substitution (S N Ar) is a substitution reaction in organic chemistry in which the nucleophile displaces a good leaving group, such as a halide, on an aromatic ring.
Once the imine is produced, it reacts with phenol in the presence of water to yield an α-aminobenzylphenol. An electron pushing mechanism for the Betti Reaction. First, the lone-pair on the nitrogen of the imine deprotonates the phenol, pushing the bonding electrons onto the oxygen.
One of the most relevant applications of the substance is the synthesis of 3-(diethylamino)phenol, key intermediate for the preparation of several fluorescent dyes (e.g., rhodamine B). Other uses for the compound include hair dye colorants and stabilizers for chlorine-containing thermoplastics. [4]
