“…The substrate was completely converted under the chosen reaction Introduction of a chlorine atom in biphenyl structure significantly affected its reactivity in the nitration process. In particular, 3-chlorobiphenyl IIa (prepared from 3-chloroaniline and benzene via the Gomberg-Bachmann reaction [17][18][19]; PCB 2 according to the BZ nomenclature accepted by IUPAC [17]) gave mainly trinitrochlorobiphenyls IIb (eight isomers) and smaller amounts of tetranitrochlorobiphenyls IIc (two isomers) (Scheme 2); the conversion of compound IIa was of 100%.…”

Nitration of mono-, di-, and trichlorobiphenyls has been studied. The nitration degree depends on the number of chlorine substituents; one to four nitro groups can be introduced. The conclusions have been confirmed by results of nitration of the "Trikhlorbifenil" technical mixture of polychlorinated biphenyls. GORBUNOVA et al. 1612 conditions to yield products of deeper nitration than were generally reported in the literature (Scheme 1). Tetranitrobiphenyls Ib (four isomers) were the major products, whereas content of the single trinitrobiphenyl isomer Ia in the products mixture was lower.

“…In order to simplify identification and quantification of congeners of polychlorinated biphenyls contained in the Trikhlorobifenil mixture, we prepared a series of di-and trichlorinated congeners of polychlorinated biphenyls under conditions of the Gomberg-Bachmann-Hey reaction [5][6][7][8] from the corresponding chloroanilines and chlorobenzenes (Table 1); the commercial certified samples (Promochem, Germany) were also used: 2,4,4'-trichlorobiphenyl (PCB-28), 2,2',5,5'-tetrachlorobiphenyl (PCB-52), and 2,2',4,5,5'pentachlorobiphenyl (PCB-101). Purity of the prepared congeners was confirmed by data of gas chromatography, chromato-mass spectrometry, and elemental analysis (Scheme 1).…”
