Plasma desulfurations were tested with nine thioethers.While aliphatic, as well as aromatic thioethers and thiophene react easily, benzothiophenes are hard to desulfurize.Predominant reaction products are low molecular alkenes and alkanes (Table 1).Addition of oxygen greatly improves the results (Table 2).

The reaction of 1,3-dithiolanes with n-butyllithium results in fragmentation to the corresponding thiocarbonyl compound followed by furhter reaction with n-butyllithium.All four types of thiocarbonyl reactions are observed: reduction, S-addition, C-addition, double addition.Synthetic applications of this reaction for the synthesis of secondary mercaptans and 1,2-carbonyl transposition (23 -> 24a-c) are described.
