Abstract
Dye intermediates of the general formula <FORM:0684625/IV (b)/1> wherein R1 and R2 each represent an alkyl, hydroxyalkyl, or aralkyl group, D represents the residue of a 5- or 6-membered heterocyclic ring system, and n is 0 or 1, are prepared by reacting two molecular proportions of a heterocyclic base of the general formula <FORM:0684625/IV (b)/2> with an excess over one molecular proportion of a compound of the general formula <FORM:0684625/IV (b)/3> wherein R3 is alkyl, aralkyl, or aryl and R4 is or as R3, in the presence of an excess over three molecular proportions of an alkyl toluene-sulphonate of the general formula <FORM:0684625/IV (b)/4> The reaction of the heterocyclic base with the intermediate <FORM:0684625/IV (b)/5> is referred to. 2-b : b -Bis-methylthiovinylbenzthiazole methiodide is prepared by heating together 2 - methylbenzthiazole, methyl p - toluenesulphonate, and methyl phenyldithiocarbamate, dissolving in ethanol, and pouring into aqueous KI. 2-b : b -Bis-ethylthiovinylbenzthiazole ethiodide, 2-b : b -bis-methylthiovinylbenzoxazole methiodide and 2-b : b -bis-methylthiovinylbenzthiazole methiodide are similarly prepared. Specifications 549,201, 549,202, 549,203, 549,204, 623,990; 678,626, 681,736 and 684,622, [all in Group IV (c)], are referred to.
