ABSTRACT

Some novel dihydropyridine derivatives viz. 4-(4-hydroxy-3-methoxyphenyl)-6-(2- hydroxyphenyl)-2-oxo-1,2-dihydro pyridine-3-carbonitrile, 4-(4-hydroxy-3-methoxyphenyl)- 6-(4-hydroxyphenyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile, 6-(4-chlorophenyl)-4-(4- hydroxy-3-methoxyphenyl)-2-oxo-1,2- dihydropyridine-3-carbonitrile, 4-(4-hydroxy-3- methoxyphenyl)-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile have been synthesized and characterization of these synthesized compounds was done by IR, 1H NMR, 13C NMR and mass analysis. The density ( I), viscosity (.) and ultrasonic velocity (U) of these dihydropyridine derivatives have been measured in dimethyl sulfoxide at different temperatures over a wide range of concentrations. From these experimental data of I, . and U, various acoustical parameters were calculated. Further, some apparent molar parameters are also calculated. The results obtained were interpreted in terms of solute.solvent and solute.solute interaction which gives idea about structure making or structure-breaking abilities of studied compounds in dimethyl sulfoxide solutions.
