type (II), react with 1,2-di(bromoseleno)benzene (I) with formation of benzo-1,3(2H)-diselenoles (III). Starting compound (I) can be easily prepared in two steps
from 1,2-diiodobenzene. If (I) is reacted with simple unactivated ketones such as acetone, cyclohexanone or cyclopentanone only bromine is eliminated from (I) and
poly(bis-1,2-phenylene) diselenide is formed. — (POTACZEK, P.; KLOC, K.;
