A mild and convenient synthesis of functionalized methyl triflones and vinyl triflones
Mahadevan, Anu,Fuchs

A general route for the synthesis of methyl triflone derivatives utilizing triflic anhydride is described. Stereoselective synthesis of E-vinyl and dienyl triflones has been accomplished by the Peterson olefination reaction of α-silyl triflone anions.
BIS-ALKYLATION OF DIMETALLATED PHENYLSULFONYLMETHYL TRIFLONE. A n+1 ANNULATION STRATEGY FOR SYNTHESIS OF CYCLIC VINYL SULFONES
Magar, S. S.,Fuchs, P. L.

Bis-metallation of phenylsulfonylmethyl triflone 4b produces a geminal dianion which can be dialkylated to afford α-phenylsulfonyl triflones.Treatment of these compounds with DBU affords vinyl sulfones which can be isomerized to allyl sulfones.
