The synthesis of symmetrical thiahexa- and thiaheptacarbocyanine dyes unsubstituted in the chain was realized by the reaction of the chloride of the tetraenedial di(N-methyl)anil with the quarternary salts of 2-methyl-3-ethylbenzothiazole, 2-methyl-3-ethyl-5-chlorobenzothiazole, 2-methyl-3-ethylnaphthothiazole, and 2-methyl-3-propyl-6,7-tetramethylenebenzothiazole and of the bromide of the tetradecapentaenedial di(N-methyl)anil with 2-methyl-3-ethylbenzothiazolium p-toluenesulfonate.
