Abstract
The reaction of 2-[3′-(3″-alkyl-2″-benzothiazolylidene)propenyl]benzothiazole,-pyridine, and -quinoline with silver ions in various solvents was studied. In anhydrous methanol, chloroform, and acetonitrile the indicated bases of cyanine dyes reduce silver ions with the liberation of acid in an amount equivalent to the silver metal formed, and the bases are partially converted to the salts. Similar reaction products are obtained by electrolysis of solutions of them in methanol and acetonitrile at the potentials established for them. It was established that the unstable salts of their N-oxides are formed in the presence of water in the reaction of the bases with silver salts; the products of the transformations of the N-oxides were identified.
