Studies on the dependence of optical activity on chemical constitution - Part XXXV. The rotatory dispersion of 5-quinolinoimino and amino-camphors (d and dl)

Abstract

(1) The rotatory dispersion of 5-quinolinoimino-d-camphor and 5-quinolinoamino-d-camphor is found in different solvents to obey Drude's one term equation, {Mathematical expression}, it is, therefore, "simple". (2) The sequence of rotatory power of 5-quinolinoamino-d-camphor in different solvents runs in the reverse order of the dielectric constants of the solvents and that in the case of 5-quinolinoimino-d-camphor follows the same order of the dielectric constants except with minor discrepencies. (3) The influence of quinoline and naphthalene ring on the rotatory power has been considered. (4) The reduction of 5-quinolinoimino-d-camphor to 5-quinolinoamino d-camphor resulting in a great lowering of its rotatory power, has been discussed. (5) The nature of the racemic form has also been investigated. (6) The d-and dl-forms of 5-quinolinoaminocamphor are found to exhibit phototropy in chloroform solution. © 1950 Indian Academy of Sciences.
