Comparison of Molar Refraction and Polarizability Constants of substituted Benzo-(4,5-d)-2-Arylimino-7-Aryl/Alkylimino-1,3,6-Thiadiazepines in Different Percentages of Solvents

Abstract

In different percentages of aetone-water and dioxane-water mixtures the
densities and refractive indices of benzo-(4,5-d)-2-phenylimino-7-phenylimino-
1,3,6-thiadiazepine (I), benzo( 4,5-d)-2-phenylimino-7-o-tolylimino-
1,3,6-thiadiazepine (II), benzo:(4,5-d)-2-phenylimino-7-m-tolylimino-
1,3,6-thiadiazepine (III), benzo-(4,5-d)-2-phenylimino-7-p-tolylilnino-
1,3;6-thiadiazepine (IV), beazo-(4,5-d)-2-phenylimino-7-o-chlorophenylimino-
1,3,6-thiadiazepine (V), benzo( 4,5-d)-2-phenylimino-7 -p-chlorophenylimino-
1,3,6-thiadiazepine (VI) and benzo-(4,5-d)-2-phenylimino-7-
t-butylimino-1,3,6-thiadiazepine (VII) have been measured. From the data
the molar refraction and polarizability constants for the compounds have
been calculated which have been used to detect the nature of dipoles and
to compare the substituted benzo-(4,5-d)-2-arylimino-7-aryl /alkylimino-
1,3,6-thiadiazepines on the basis of presence of different substituents.
