Abstract

Dye intermediates are prepared by reacting a cyanine dye of the general formula <FORM:0638023/IV (b)/1> wherein R1 and R2 are each an alkyl, hydroxalkyl, aralkyl, or hydroxyaralkyl group, D1 and D2 are each the residue of a 5- or 6-membered heterocyclic nitrogen ring, n is 0 or 1, x is 1 or 2, and A is an acid radical, with an acid HX and a trithio-orthoformate of formula HC(SR3)3, wherein R3 is an alkyl or aralkyl group, in presence of a carboxylic acid or anhydride which is a solvent for the reactants. 1 - Ethylthio - 2 : 4 - di - a - quinolyl - 1 : 3-butadiene diethiodide is prepared by refluxing together 1 : 11 - diethyl - 2 : 21 - quinocarbocyanine iodide, toluene-p-sulphonic acid, triethyl trithio-orthoformate, and acetic anhydride, distilling off the solvent in vacuo, dissolving in ethyl alcohol, and pouring into aqueous KI solution. 1-Ethylthio-2 : 4-dibenzthiazolyl - 1 : 3 - butadiene monoethiodide monoetho - p - toluenesulphonate, 1 - ethylthio - 2 : 4-dibenzthiazolyl - 1 : 3 - butadiene di - etho - p-toluenesulphonate, 1 - methylthio - 2 : 4 - dibenzthiazolyl - 1 : 3 - butadiene di - etho - p-toluenesulphonate, 1 - benzylthio - 2 : 4 - dibenzthiazolyl - 1 : 3 - butadiene di - etho - p - toluenesulphonate, 1 - ethylthio - 2 : 4 - di - (51 - methyl-21 - benzthiazolyl - 1 : 3 - butadiene monoetho-p - toluenesulphonate monoethiodide, 1 - ethylthio - 2 : 4 - di - (51 - methyl - 21 - benzthiazolyl) 1 : 3 - butadiene di - ethiodide, 1 - ethylthio-2 : 4 - di - (51 - chloro - 21 - benzthiazolyl) - 1 : 3-butadiene di - etho - p - toluenesulphonate, 1 - ethylthio - 2 : 4 - di - (51 - chloro - 21 - benzthiazolyl) - 1 : 3 - butadiene di - ethiodide, 1-ethylthio - 2 : 4 - di - (41 : 51 - benzbenzthiazolyl) 1 : 3 - butadiene di - etho - p - toluenesulphonate, 1 - ethylthio - 2 : 4 - di - (41 : 51 - benzbenzthiazolyl) - 1 : 3 - butadiene diethiodide, 1-benzylthio - 2 : 4 - di - (41 : 51 - benzbenzthiazolyl) - 1 : 3 - butadiene di - etho - p - toluenesulphonate, 1 - ethylthio - 2 : 4 - di - a - quinolyl-1 : 3 - butadiene di - ethobromide, 1 - ethylthio-2 : 4 - di - a - quinolyl - 1 : 3 - butadiene monoethobromide mono - etho - 21 - naphthalenesulphonate, 1 - ethylthio - 2 : 4 - di - g - quinolyl-1 : 3 - butadiene monoethobromide mono - etho-p - toluenesulphonate, 1 - ethylthio - 2 : 4 - di-g - quinolyl - 1 : 3 - butadiene diethiodide, 1 - ethylthio - 2 : 4 - dibenzelenazolyl - 1 : 3-butadiene di - etho - p - toluenesulphonate, 1-ethylthio - 2 : 6 - di - (31 : 31 - dimethylindolenyl) 1 : 3 : 5 - hexatriene monomethiodide monometho - p - toluenesulphonate, 1 - ethylthio - 2 : 6-di - (51 - methyl - 21 - benzthiazolyl) - 1 : 3 : 5-hexatriene mono - ethiodide mono - etho - p-toluenesulphonate, and 1 - ethulthio - 2 : 6 - di-(51 - chloro - 21 - benzthiazolyl) - 1 : 3 : 5-hexatriene mono - ethiodide mono - etho - p-toluenesulphonate are similarly prepared. Specification 638,024, [Group IV (c)], is referred to.
