Nitro-containing biphenyls

Mixed donor ligands. The reaction of [Fe(salen)] with a range of quinones yields [(Fe(salen) 2(quin)] (quin = p-benzoquinone, tetramethyl-p-benzoquinone, and tetrachloro-p-benzoquinone) which probably contain quinone ligands. With 9,10-phenanthraquinone and 1,2-naphthaquinone, [Fe(salen)(quin)] is formed. The reactions of Fe(salen) with a variety of organic halides and nitro- and nitroso-compounds have been studied. With PhN02, [Fe (salen)20], and PhN(0)=NPh are formed whereas the PhNO reaction yields the same iron(iii) compound and PhN=NPh. Reaction with RNO (R = 2-biphenyl or... 

Kim et al. [49] prepared PBPOs containing two -CF3 groups positioned symmetrically on one phenyl ring from 4 -hydroxy-4-nitro-2,6-fcw-(trifluoromethyl)biphenyl and its 3 -isomer through a... 

The retention of 34 nitrated PAH compounds (e.g., quinolines, naphthalenes, biphenyls, anthracenes, fluorenes) was studied on a Cjg column using mobile phases consisting of 50/50, 60/40, and 70/30 mixtures of acetonitrile/water at 35°C, 45 C, 55°C, and 65°C [179]. Aliquots (1 pL) of sanqiles containing 1 mg/mL of each compound were injected. The log K value was tabulated for each compound under each mobile phase/temperature combination. This is an excellent reference for those seeking detailed information on the retention behavior of nitro-PAHs.
