Ethyl 4-hydroxy-9-tosyl-9H-carbazole-3-carboxylate
(Int Union Crystallography, 2009)
In the title compound, C22H19NO5S, the carbazole skeleton is nearly planar [maximum deviation = 0.043 (1) angstrom] with the pyrrole ring oriented at dihedral angles of 2.32 (6) and 1.77 (6)degrees with respect to the ...
Spectroscopic determination of acid dissociation constants of some pyridyl Shiff bases
(American Chemical Society, 2006)
The acid dissociation constants (pK(a)) of eight biologically active pyridyl Shiff bases were determined using a UV-vis spectroscopic technique at 25 +/- 0.1 degrees C. The first acidity constants (pK(a1)) of the ...
Synthesis, spectral studies of salicylidine-pyridines: Crystal and molecular structure of 2-[(1E)-2-aza-2-(5-methyl (2-pyridyl)ethenyl)]-4-bromobenzen-1-ol
(Pergamon-Elsevier Science LTD, 2007)
Schiff bases derived from different meta-substituted salicylaldehyde and 5-methylaminopyridine have been synthesized and characterized by elemental analysis, FT-IR, NMR and UV-vis techniques. NMR assignments were made using ...
