2-aminobiphenyl is a chemical compound from the group of aromatic amino compounds .

Extraction and presentation

According to Shudo and Akamota, 2-aminobiphenyl can be obtained by reducing nitrobenzene with zinc in benzene in the presence of trifluoromethanesulfonic acid, although the majority of 4-aminobiphenyl , aniline and, in small amounts, 4-aminoterphenyl are formed.

properties

2-aminobiphenyl is a beige, flammable solid with a characteristic odor. The substance is practically insoluble in water. The isomeric 4-aminobiphenyl, which is known to be carcinogenic , also occurs as an impurity .

use

2-aminobiphenyl can be used to produce carbazole derivatives by oxidation .
