The reductive amination of aliphatic ketones in aqueous solutions of primary amines was realized by an electrochemical method.The best yields of the secondary amines were obtained at lead and cadmium cathodes in an aqueous electrolytic solution at pH 11-12.Elongation and branching in the carbon chain of the radicals both of the ketone and of the primary amine lead to a reduction in the yield of the secondary amine.The yield of the secondary amine is mainly determined by the rate of the chemical reaction leading to the formation of the azomethine compound, preceding the electrochemical reduction stage.

The compound 3,7-dicyano-1,4-dithiino[2,3-c; 6,5-c']diisothiazole is prepared by reacting either tetracyano-1,4-dithiin or 4,5-dicyano-1,3-dithiolen-2-one with sulfur in 1,2-dimethoxyethane at a temperature of 50°-280° C in the presence of a basic catalyst. The diisothiazole can be converted to derivatives with various utilities, e.g., as fluorescent brighteners.
