Abstract

The structure of 2-methylthieno[2, 3-g]benzothiazole, previously obtained by potassium ferricyanide oxidation of 5-thioacetylaminothionaphthene in alkaline solution, is proved. A synthesis of this base is effected by heating 5, 5′-diacetylamino-4, 4′-dithionaphthenyldisulfide with zinc dust in acetic acid-acetic anhydride. Quino-(2)monomethyl-, carbo-, mero-, dimero-, and thiocyanato dyes are obtained, as well as styryl dyes containing a thieno[2, 3-g]benzothiazole group, and their colors are investigated.
