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, the tautomerisation into cycloalkadienethiols (...

Description
Summary: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, the tautomerisation into cycloalkadienethiols (10, 11) occurred at 77 K. As for the cyclobutenethione 13, only the ring opening products were observed at 77 K.
