Theoretical and Spectroscopical Investigations of Indigo Dyes, XXII. - Preparations of 5,5'- and 6,6'-Dialkylated Indigo Dyes

The manifolded applicabilities of indigo dyes are strongly restricted by the low solubility of most of their representatives.We describe in this paper the preparation of a series of dialkylated indigos 1, thioindigos 2, dyes of the cibaviolett-type 3, and of the corresponding vinylogues 4, 5, and 6 by different synthetic methods.Some of the prepared compounds show a remarkable solubility and can be used for spectroscopic measurements even in non-polar solvents.
