WebSynthesis of biphenyl products The mixture solution of aniline derivatives (30 mmol) and 1,4-methyl-bezene (40.0 mL) was added dropwise into a mixture of 1,4-dimethyl-benzene (20.0 mL), isopropyl nitrite, as prepared above, and CuCl (1.00 g, 10mmol). The reaction was mechanically stirred for 3 h at room temperature. Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene or BP) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes … See more Biphenyl occurs naturally in coal tar, crude oil, and natural gas and can be isolated from these sources via distillation. It is produced industrially as a byproduct of the dealkylation of toluene to produce methane: The other principal … See more Lacking functional groups, biphenyl is fairly non-reactive, which is the basis of its main application.
