The reaction of fused 1, 2, 3-selenadiazole with 4-t-butyl-1, 2, 3-selenadiazole as the precursor of seleniumatom yielded 1, 2-diselenone, which gave the [2+4] cycloadducts in the presence of olefins.

Sterically protected fused 1,2,3-thiadiazole and 1,2,3-selenadiazole were heated with molten sulfur resulting in a ready formation of fused cyclopolysulfides, the photolysis of which in the presence of olefins afforded the cycloadducts via the initially formed 1,2-dithione and 1,2-selenoxothione.
