Abstract
A dye intermediate is prepared by heating a compound of the forumula of Fig. 1. <PICT:0595785/IV/1> wherein R is an alkyl or aralkyl group and D a chain of 3 methylene groups, any of which may be hydrocarbon-substituted with an alkyl or aralkyl quaternary salt of a 5- or 6-membered heterocyclic nitrogen compound containing a reactive methylene group in a - or g -position to the quarternary nitrogen atom or a 5-membered heterocyclic nitrogen keto-methylene compound, the reaction being effected in presence of a non-basic compound which will combine with the liberated mercaptan RSH. The first compound may be D 2 : 3 - (3 - ethylthio - 5 : 5 - dimethyl)-cyclohexenone (1), D 2 : 3 - (3-ethylthio - 5 - phenyl) - cyclohexenone (1), D 2 : 3 - (3 - ethylthio - 5 - methyl) - cyclohexenone (1), or D 2 : 3 - (3 - ethylthio) - cyclohexenone (1), or an analogous compound prepared as in Specification 595,783 from 5-isopropylcyclohexanedione (1 : 3), 4 : 5 : 5-trimethylcyclohexanedione (1 : 3), 4 - phenyl - 5 : 5 - dimethylcyclohexanonedione (1 : 3), or 5-styrylcyclohexanedione (1 : 3). The non-basic compound may be acetic anhydride. Examples are given of the preparation of intermediates (1) by fusing together D 2 : 3-(3-ethylthio - 5 : 5 - dimethyl) - cyclohexenone (1), 1 - methylbenzthiazole, and methyl p-toluenesulphonate, adding acetic anhydride, refluxing and pouring into aqueous KI solution; (2) to (4) by proceeding similarly to example (1), but obtaining the methyl-p-toluenesulphonate, the ethiodide, and the ethyl-p-toluenesulphonate respectively; (5) by proceeding similarly to example (1), but using ethyl-p-toluenesulphonate and quinaldine; (6) by proceeding similarly to example (1), but using ethyl-p-toluenesulphonate and p-toluquinaldine; (7) by fusing together 1-methylbenzthiazole and ethyl p-toluenesulphonate, adding D 2 : 3-(3-ethylthio-5-methyl) - cyclohexenone (1), refusing, adding acetic anhydride, and refluxing; (8) by fusing together 1 - methylbenzthiazole, methyl p-toluenesulphonate, D 2 : 3 - (3-ethylthio)-cyclo - hexenone (1), adding acetic anhydride, and boiling; (9) by fusing together N-methylrhodanine and D 2 : 3 - (3 - ethylthio - 5 : 5 - dimethyl)-cyclohexenone (1), adding acetic anhydride and boiling; and (10) by fusing together 1-phenyl-3-methyl-5-pyrazolone and D 2 : 3-(3-ethylthio - 5 : 5 - dimethyl) - cyclohexenone (1), adding acetic anhydride, and boiling. Specification 595,784 also is referred to.
