producing a rather stablecarboniumion, the thioether gives the chloride and an olefin, which are derived from the cation, the latter reacting also with the sulfenyl chloride to give adducts. There is another path to afford alkyl chloride; that is, an SN2-type reaction takes place when the alkyl part gives a less stablecarboniumion. The third and fourth products are α-chloro sulfide and α,β-unsaturated

[GRAPHICS]The synthetic scope and mechanism of the fragmentation of cyclic beta-sulfenyl enol triflates to give alpha-sulfenyl enones are described. This transformation is the central step in a mild, functional group-tolerant method for preparing alpha-sulfenyl enones.
