✦ Synopsis

Trifluoromethanethio-and trifluoromethaneselenosulfonates are strong electrophilic reagents which add rapidly to olefins to deliver fl-sulfenyl and p-selenyl triflones. These products are converted in high yields to vinyl triflones by different techniques under mild conditions. This two-step procedure is an efficient route to vinyl triflones from non-functionalized olefins.

Radical attack on the double bond of 2,3-bis(phenylsulfonyl)-1 -propene leads to an intermediate sulfonyl stabilized radical. This species readily fragments to produce a new vinyl sulfone which can undergo further radical cyclization to give a six ring sulfone.
