Abstract
Dyes of the general formula <FORM:0599693/IV/1> wherein L represents a methine group, R a substituted or unsubstituted alkyl group, R1 and R11 substituted or unsubstituted alkyl or aryl groups, and Z the non-metallic atoms to complete a heterocyclic nucleus (e.g. a benzthiazole, benzoxazole, or b -naphthathiazole nucleus) are prepared by quaternising dyes of the formula <FORM:0599693/IV/2> by heating with an alkyl salt and condensing the quaternary salt formed with a compound of the formula <FORM:0599693/IV/3> in the presence of an acid-binding agent (e.g. pyridine or triethylamine), with heating under reflux if necessary. 5 - (3 - Ethyl - 2 - benzthiazolylidene) - 3 - ethyl - 2 - (3 - ethyl - 4 - oxo - 2 - thiono - 5 - thiazolidylidene) - 4 - thiazolidone is prepared by heating together 3 - ethyl 5 - (3 - ethyl - 2 - benzthiazolylidene) - rhodanine and methyl p-toluenesulphonate in nitrobenzene, diluting the cooled solution with acetone and adding aqueous potassium iodide to give 5 - (3 - ethyl - 2 - benzthiazolylidene) - 2 - methylthiol-4-thiazolone ethiodide, and heating this with 3-ethylrhodanine in pyridine. 2-(3-Carbethoxymethyl-4-oxo-2-thio-5-thiazolidene) -3-ethyl-5-[(3-ethyl-2-benzthiazolylidene) -ethylidene]-4-thiazolidone is prepared by refluxing together 5-[(3-ethyl-2-benzthiazolylidene)-ethylidene] - 2 - methylthiol - 4 - thiazolone ethiodide, 3-carbethoxymethylrhodanine, trimethylamine and absolute ethyl alcohol. 3 - Ethyl - 5 - [(3 - ethyl - 5 - methyl - 2 : 1 : 3 : 4 - thiadiazolylidene) - ethylidene] - rhodanine is prepared by refluxing together 2 : 5-dimethyl-1 : 3 : 4 - thiadiazole ethiodide, 5 - acetanilido - methylene - 3 - ethylrhodanine, absolute ethyl alcohol and triethylamine. 2 : 5-Dimethyl-1 : 3 : 4-thiadiazole ethiodide is prepared by heating together in a sealed tube 2 : 5-dimethyl-1 : 3 : 4-thiadiazole and ethyliodide. Specifications 450,958; 498,290 and 515,372, [both in Group XX], are referred to.
