3-Hydrory-6-bromo-thionaphthene was condensed with isatin and some of its different types of substitution products. The resulting 3-indole-2'-(6'-bromo) thionaphtheneindigos are found lighter than those of the corresponding 7'-bromo compoundsI from a comparative study of their colour, dyed shade and absorption maxima dat
