Abstract: The bis(arylimino)pyridines, 2-[CMeN{2,6-{(4-FC6H4)2CH}2-4-NO2}]-6-(CMeNAr)C5H3N (Ar = 2,6-Me2C6H3 L1, 2,6-Et2C6H3 L2, 2,6-i-Pr2C6H3 L3, 2,4,6-Me3C6H2 L4, 2,6-Et2-4-MeC6H2 L5), each containing one N'-2,6-bis{di(4-fluorophenyl)methyl}-4-nitrophenyl group, have been synthesized by two successive condensation reactions from 2,6-diacetylpyridine. Their subsequent treatment with anhydrous… read more here.

Abstract: Abstract A complete multinuclear magnetic resonance characterization of α,α-bis(4-fluorophenyl)-β-methyl-1H-imidazole-1-ethanol (a representative carbinoloimidazole topical anti-inflammatory agent) is presented, the first such assignment of a compound with diastereotopic fluorophenyl rings. The relative orientation of the 4-fluorophenyl rings… read more here.
