Abstract
Dyes are prepared by reacting a compound of the general formula <FORM:0634952/IV (c)/1> wherein D is the residue of a 5- or 6-membered heterocyclic nucleus, with an alkyl or aralkyl quaternary salt of a heterocyclic nitrogen compound having as a substituent in the a - or g -position to the quaternary N atom a group of the formula -(CH=CH)mSR or -(CH=CH)mSeR, wherein R is an alkyl, aralkyl, or aryl group and m is O or a positive integer, or a group of the formula -(CH=CH)n-NH2, wherein n is a positive integer or a N-aryl, N-acyl, or N-acylaryl derivative thereof. The dyes may also be obtained by using the corresponding intermediates of formula <FORM:0634952/IV (c)/2> wherein R s H or a hydrocarbon group with a dehydrating solvent such as acetic or propionic anhydride. Dyes are prepared by boiling together in alcohol containing triethylamine (1) 2 : 3-(benziminazo-11 : 21-thi-azolidone-4 and 2-o -ethylmercaptovinylbenzoxazole metho-p-toluenesulphonate; (2) 2 : 3-(benziminazo - 11 : 21) - thiazolidone - 4 and 2 - o - acetanilidovinylbenzthiazole ethiodide; (3) 2 : 3 - (benziminazo - 11 : 21) - thiazolidone-4 and 2 - methylmercaptobenzthiazole methiodide; and (4) 2 : 3 - (benziminazo - 11 : 21)-thiazolidone - 4 and 2 - o - acetanilidovinyl-3 : 3- dimethylindolenine methiodide, and by heating together in pyridine containing acetic anhydride; (5) S - [6 - keto - 4 - methyl-dihydropyrimidyl - (2)] - thioglycollic acid and 2 - o - acetanilidovinyl - 3 : 31 - dimethylindolenine methiodide; (6) S - [6 - keto - 4-methyldihydropyrimidyl - (2)] - thioglycollic acid and 2-methylmercaptobenzthiazole methiodide; (7) S-[4-ketodihydroquinazolyl-(2)]-thioglycollic acid and 2-o -acetanilidovinyl-3 : 3-dimethylindolenine methiodide; (8) S-[4 - ketodihydroquinazolyl - (2)] - thioglycollic acid and 2-methylmercaptobenzthiazole methiodide; and (9) 5-methyl-1 : 3 : 4-triazole-2-thioglycollic acid and 2-o -acetanilidovinyl-3 : 3 - dimethylindolenine methiodide. Specifications 425,609 and 634,951, [Group IV (b)], are referred to.
