REACTIONS OF POLYMETHINE DYES. I. SYNTHESIS OF THE PSEUDOBASES OF POLYMETHINE DYES AND THEIR TRANSFORMATIONS

Nonsalt-like benzene-soluble pseudobases are formed in the reaction of polymethine dyes with sodium alcoholates.The presence of ionized and un-ionized forms of the pseudobases was established by electronic absorption spectra in aprotic solvents.Solutions of these compounds in alcohols only contain the ionized forms; the unionized form predominates in benzene solutions.The action of various acids on the pseudobases leads to the production of polymethine dyes with the respective anions.
