Abstract
Meso-substituted cyanine dyes are prepared by reacting an alkyl or aralkyl quaternary salt of a benzthiazole containing a thioether grouping in the 2-position with an alkyl or aralkyl quaternary salt of a benzthiazole containing an alkyl-or aralkyl-substituted methyl group in the 2-position, in the presence of a strong base, which is substantially stronger than pyridine and should be at least as strong as triethylamine. Sodium ethoxide may be used. 3 : 31 : 8-Trimethylcyanine iodide is prepared by boiling together in alcohol 2-ethylbenzthiazole methiodide, 2-methylthiobenzthiazole methiodide, and sodium ethoxide or triethylamine. 3 : 31 - Diethyl - 8 - methylthiacyanine iodide is similarly prepared. Specification 424,559 is referred to.
