Abstract

Cyclammoniumpolymethine dyes.--Basic dyes are obtained by causing a carbon tetrahalogenide to react upon a base derived from a heterocyclic ammonium salt containing a reactive methyl group in the a -position with respect to the nitrogen. The products contain three molecules of the starting material combined to form a carbocyanine, and dye tannin-mordanted cotton clear red to blue shades. In examples (1) 1 : 3-3-trimethyl-2-methylene indoline base is heated with carbon tetrachloride or tetrabromide (dyes red-violet shades): (2) 6-acetylamino-1 : 3 : 3-trimethyl-2-methylene indoline (prepared by reducing the 6-nitro-1 : 3 : 3-trimethylmethyleneindoline and adding the theoretical quantity of acetic anhydride to the amino base in ether) is heated with carbon tetrachloride (dyes blueish-violet): (3) N-methyl-2-methylenebenzthiazoline is heated with carbon tetrachloride (dyes brownish-violet): (4) the base from N-ethylquinaldine iodide is heated with carbon tetrachloride (dyes blueish-violet).
