The 2-(2'-Thienyl)-(IVb) and 4-bromo-2-(2'-thienyl)-benzofuro benzothiazole (VII) were prepared by the oxidation of 3-(2'-thiothenoyl)amino-(III)- and 2-bromo-3-(2'-thiothenoyl)amino-dibenzofuran (IV) with potassium ferricyanide in basic solution.The angular structure IVb is demonstrated by IR, 1H-NMR and chemical method.
