The reactive unsubstituted cyclohex-2-enethione (1) and cyclopent-2-enethione (2) have been synthesized in two steps (yields ca 70%) from the corresponding cycloalkenyl bromides. The key step is a retro-ene reaction under FVT conditions. The purple-blue thioketones 1 and 2, polymerizing rapidly abov
