Generation by retro-ene reaction of cyclohex-2-enethione and cyclopent-2-enethione

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 above -80°C in the condensed phase, have been characterized by UV-visible and IR spectroscopy at -196°C, as well as, in the gas phase, by direct FVT/HRMS coupling. The reaction of 2 with diazomethane in THF led to 1,3-dithiolane 9.

Access to new reactive unsaturated cycloalkenethiones by flash vacuum thermolysis

The reactive conjugated cycloalkenethiones (3, 4, 5) have been synthesized from the corresponding cycloalkenylsulfanyl compounds under flash vacuum thermolysis (FVT) conditions. The nonconjugated cycloalkenethiones (8, 9) were prepared in the same way, th
