Synthesis of sulfines by oxidation of trithioperesters and their rearrangement into acyltrisulfides
摘要:
Trithioperesters were synthesised by sulfenylation of halomagnesium alkanedithioates with alkylthiotoluenesulfonates and oxidised by mCPBA. The chemoselective conversion of a thiocarbonyl group into a sulfine moiety was achieved in three cases to yield the first examples of trithioperester sulfines. These compounds undergo at room temperature a novel rearrangement to acyltrisulfides.
