A number of selenium‐ 2 and tellurium bis(dithiocarboxylates) 3 have been prepared by the reaction of piperidinium or sodium dithiocarboxylates 1 with sodium seleno‐ and telluropentathionates. The orange or red products are stable towards heat and moisture. It was found that 2 and 3 react with halogens and N ‐chloro‐ and N ‐bromosuccinimide to give the corresponding haloselenium‐ 4 , 5 and halotellurium dithiocarboxylates 6 – 8 in good yields. The n →π* transitions of the thiocarbonyl groups in 2 – 8 are observed in a region of shorter wavelengths (hypsochromic shift) than those of the corresponding bis(thioacyl) trisulfides and dithio‐ and thioneselenol esters.
