Ciusa, W. published the artcileThe ultraviolet spectra of the m- and p-substituted N-alkyl derivatives of pyridine, Recommanded Product: N,N-Diethylisonicotinamide, the publication is Bollettino Scientifico della Facolta di Chimica Industriale di Bologna (1959), 12-26, database is CAplus.
cf. CA 53, 5398e; 53, 20059d. Pyridine derivatives, prepared as described in earlier publications, were dissolved in 0.1N NaCl (pH 6-7), 0.1N HCl (pH 1.1), and in 0.1N NaOH (pH 13.0) to give 0.1-0.05M solutions and their ultraviolet spectra obtained for the range 210-460 mμ at 20 ± 2°. These were presented in 37 absorption curves. The λmaximum and the extinction (ε × 10-3) at this wave length in HCl, NaCl, and NaOH for these compounds were: pyridine, 256, 5.4, 3.4, 2.5; methylpyridinium (I) iodide, 260, 4.5, 4.4, 4.8; I bromide, 258, 4.5, 4.5 4.5; I chloride, 258, 4.7, 5.0, 4.9; dodecylpyridinium bromide, 260, 4.0, 3.5, 4.1; myristylpyridinium bromide, 260, 4.5, 4.1, 4.6; cetylpyridinium (II) bromide, 260, 3.4, 3.1, 3.5; II chloride, 260, 4.8, 4.6, 4.8; octadecylpyridinium bromide, 260, 4.9, 3.5, 4.0; Et ester of nicotinic acid (III), 260 (265, 262), 5.0, 2.7, 3.0; III MeI salt, 265, 4.5, 3.9, 4.0; III MeBr salt, 265, 4.5, 4.3, 4.0; III MeCl salt, 265, 4.2, 4.3, 3.4; III BuBr salt, 265, 4.2, 4.3, 3.4; III iso-AmBr salt, 265, 4.5, 4.3, 4.3; nicotinic acid (IV), 261 (262, 264), 4.9, 3.6, 2.8; IV MeI salt, 265, 4.3, 4.9, 4.0; trigonelline, 265, 4.0, 3.8, 4.0; IV amide, 260, 4.8, 3.3, 3.0; IV amide-MeI, 265, 4.9, 4.6, 4.8; IV monomethylamide, 262, 5.7, 3.6, 3.5; IV diethylamide (V), 262, 5.2, 3.6, 3.3; V MeCl salt, 268, 4.3, 4.8, 4.6; V EtCl salt, 268, 4.0, 3.8, 3.8; V iso-PrCl salt, 268, 3.5, 3.5, 3.8; V AmCl salt, 265, 4.0, 3.8, 3.0; V AcCl salt, 268, 4.0, 3.8, 3.6; Et ester of isonicotinic acid (VI), 272 (272, 265), 4.5, 2.8, 2.8; VI MeI salt, 275 (278, 268), 4.5, 4.6, 4.4; VI EtBr salt, 275 (268, 265), 4.1, 3.5, 4.1; VI decyl bromide, 275 (278, 265), 4.3, 3.9, 3.5; isonicotinic acid (VII), 270 (263, 265), 4.1, 3.2, 2.1; isotrigonelline, 272 (265, 265), 3.9, 3.9, 4.1; VII amide, 262 (266, 266), 5.0, 2.8, 2.6; VII amide-MeI, 268 (266, 264), 4.7, 4.8, 4.5; VII diethylamide (VIII), 259 (259, 258), 6.3, 3.3, 3.2; VIII MeCl salt, 262, 5.9, 5.9, 5.7; VIII EtCl salt, 262, 5.8, 5.8, 5.5; VIII cetyl chloride, 262, 6.1, 6.3, 5.7. The lack of influence by CO2H or CO2R groups was in disagreement with findings by Black (CA 49, 15389h).
