Biphenyl 4-amino

Kadlubar, F.F. unpublished studies with N-hydroxy-4-amino-biphenyl and N-hydroxy-N1-acetylbenzidine. 

There are no reports on carcinogenicity of PNB in humans. However, PNB was used as an intermediate in the preparation of 4-amino-biphenyl, a recognized human bladder carcinogen, and bladder tumors found in men exposed to 4-aminobiphenyl may have been partially due to PNB. ... 

So erhalt man z.B. aus Azido-benzol und Benzol (X = H) ein Gemisch von (2-Amino-phenyl) -phenyl-amin (73%), 2-Amino- (8%) und 4-Amino-biphenyl (8%). Wahrend in ana-logen Fallen ahnliche Gemische entstehen, erhalt man unter gleichen Bedingungen aus Azidobenzol und Naphthalin 1-Anilino-naphthalin (78%) und aus 1-Azido-naphthalin und Benzol (l-Amino-4-phmyl-naphthalin (82%). 

The isomer 3,5-dinitro-4-methy 1 amino-biphenyl is described in Beil 12,[762] and the isomer 3,4 -dinitro-4-amino-biphenyl-methane in...

Thus, for instance, mixed acetonitrile + aqueous HCl solvents have been used for polymerization of the aromatic amine 4-amino-biphenyl [21], and hydrocarbons such as toluene may be mixed with acetonitrile to facilitate solution of monomers such as pyrene. 

As an example of a relatively simple structural determination, Catellani et al. [415b] took a strong absorption at 920 cm in the spectra of a family of substituted poly(2,5-thienylene vinylene)s to indicate a trans configuration about the vinyl bond. In studies of typical poly(aromatic amines) such as poly(diphenyl amine), poly(4-amino biphenyl) and poly(A/-Phe-2-naphthyl amine), the Dao group [24,46] observed...
