It has been shown in the preceding paper13 of these dyes, the anil I and 3-ethyl-2- methylthat the condensation of phenylnitrone of 3-benzothiazolium iodide were reacted by refluxethyl-2-formylbenzothiazolium iodide and 3-ing for a short time (8~ 15 min.) in pyridine ethyl-2-methylbenzothiazolium iodide in pyridi-and, in this case, 3, 3-diethyl-9-(3-ethyl-l-thia- 3-ne gave four kinds of dyes and their structures azoniainden-2-yl) thiacarbocyanine ...
